- SiO 2 is 0 wt% to 15 wt%
- Al 2 O 3 is 0 wt%.
- a material composition that does not contain a lead component, such as ⁇ 10 wt%, may be included. Furthermore, there are no particular limitations on the content of these material compositions.
- the dielectric material composed of these composition components is pulverized by a wet jet mill or a ball mill so as to have an average particle diameter of 0.5 ⁇ m to 2.5 ⁇ m.
- the pulverized dielectric material is a dielectric material powder.

- the layer paste is completed.
- the binder component of the second dielectric layer paste is the same as the binder component of the first dielectric layer paste.
- the second dielectric layer paste is printed on the first dielectric layer 81 by a die coating method or a screen printing method.
- the printed second dielectric layer paste is fired through a drying process.
- the firing temperature is 550 ° C. to 590 ° C., which is a little higher than the softening point of the dielectric material.
- the film thickness of the dielectric layer 8 is preferably 41 ⁇ m or less in total for the first dielectric layer 81 and the second dielectric layer 82 in order to ensure visible light transmittance.
- the content of Bi 2 O 3 in the first dielectric layer 81 is more than the content of Bi 2 O 3 in the second dielectric layer 82 in order to suppress reaction with Ag contained in the metal bus electrodes 4b and 5b. There are also many. Therefore, the visible light transmittance of the first dielectric layer 81 is lower than the visible light transmittance of the second dielectric layer 82. Accordingly, the film thickness of the first dielectric layer 81 is preferably smaller than the film thickness of the second dielectric layer 82.
- Bi 2 O 3 is 11% by weight or less, coloring is less likely to occur. However, bubbles are likely to be generated in the second dielectric layer 82.

- the content of at least one selected from O 3 and MnO 2 is preferably 0.1% by weight or more. Furthermore, 0.1 to 7 weight% is more preferable. In particular, when it is less than 0.1% by weight, the effect of suppressing yellowing is small. If it exceeds 7% by weight, the glass is colored, which is not preferable.
- the dielectric layer 8 in the present embodiment suppresses the yellowing phenomenon and the generation of bubbles in the first dielectric layer 81 in contact with the metal bus electrodes 4b and 5b containing Ag. Further, a high light transmittance is realized by the second dielectric layer 82 provided on the first dielectric layer 81.

- the point C is a peak in the (111) plane orientation of the base film 91 formed of two of MgO and BaO.
- the diffraction angle at point A is 36.1 degrees.
- the point A exists between the peak of the (111) plane orientation in the MgO body that is the first metal oxide and the peak of the (111) plane orientation in the CaO simple substance that is the second metal oxide.
- Point B exists between the peak of the (111) plane orientation in the MgO simple substance that is the first metal oxide and the peak of the (111) plane orientation in the SrO simple substance that is the second metal oxide.

- the plane orientation (111) is exemplified. However, the same applies to other plane orientations.
- the depth from the vacuum level of CaO, SrO and BaO exists in a shallow region as compared with MgO. Therefore, when driving a PDP, when electrons existing in the energy levels of CaO, SrO, and BaO transition to the ground state of Xe ions, the number of electrons emitted by the Auger effect is less than the energy level of MgO. It is thought that it will increase compared to the case of transition.
- the peak of the base film 91 in the X-ray diffraction analysis is between the peak of the first metal oxide and the peak of the second metal oxide. That is, it is considered that the energy level of the base film 91 exists between single metal oxides, and the number of electrons emitted by the Auger effect is larger than that in the case of transition from the energy level of MgO.
- the base film 91 according to the present embodiment can exhibit better secondary electron emission characteristics as compared with MgO alone.
- the sustain voltage can be reduced.
- the discharge voltage can be reduced when the Xe partial pressure as the discharge gas is increased in order to increase the luminance. That is, a low-voltage and high-luminance PDP 1 can be realized.
- Aggregated particles 92 are formed by aggregating a plurality of MgO crystal particles 92a, which are metal oxides. The agglomerated particles 92 are preferably distributed uniformly over the entire surface of the base film 91. This is because the variation of the discharge voltage in the PDP 1 is reduced.
- the MgO crystal particles 92a can be manufactured by either a gas phase synthesis method or a precursor firing method.
- a gas phase synthesis method first, a metal magnesium material having a purity of 99.9% or more is heated in an atmosphere filled with an inert gas. Furthermore, metallic magnesium is directly oxidized by introducing a small amount of oxygen into the atmosphere. In this manner, MgO crystal particles 92a are produced.
- the MgO precursor is uniformly fired at a high temperature of 700 ° C. or higher.
- MgO crystal particles 92a are produced.
- the precursor include magnesium alkoxide (Mg (OR) 2 ), magnesium acetylacetone (Mg (acac) 2 ), magnesium hydroxide (Mg (OH) 2 ), magnesium carbonate (MgCO 2 ), and magnesium chloride (MgCl 2 ). ), Magnesium sulfate (MgSO 4 ), magnesium nitrate (Mg (NO 3 ) 2 ), or magnesium oxalate (MgC 2 O 4 ). Depending on the selected compound, it may usually take the form of a hydrate.
- Hydrate can also be used as a precursor.
- the compound as the precursor is adjusted so that the purity of magnesium oxide (MgO) obtained after firing is 99.95% or higher, desirably 99.98% or higher. If a certain amount of impurity elements such as various alkali metals, B, Si, Fe, and Al are mixed in the precursor compound, unnecessary interparticle adhesion and sintering occur during heat treatment. As a result, it becomes difficult to obtain highly crystalline MgO crystal particles. Therefore, it is preferable to prepare the precursor in advance, such as removing the impurity element from the compound.
- a dispersion is prepared by dispersing the MgO crystal particles 92a obtained by any of the above methods in a solvent. Next, the dispersion is applied to the surface of the base film 91 by spraying, screen printing, electrostatic coating, or the like. Thereafter, the solvent is removed through a drying / firing process. Through the above steps, the MgO crystal particles 92 a are fixed on the surface of the base film 91.
- the aggregated particles 92 are those in which crystal particles 92a having a predetermined primary particle size are aggregated or necked. In other words, it is not bonded as a solid with a large bonding force, but a plurality of primary particles form an aggregate body due to static electricity, van der Waals force, etc., and due to external stimuli such as ultrasound , Part or all of them are bonded to such a degree that they become primary particles.
- the aggregated particles 92 have a particle size of about 1 ⁇ m, and the crystal particles 92a preferably have a polyhedral shape having seven or more faces such as a tetrahedron and a dodecahedron. .
- the particle size of the primary particles of the crystal particles 92a can be controlled by the generation conditions of the crystal particles 92a.
- the particle size can be controlled by controlling the firing temperature or firing atmosphere.
- the firing temperature can be selected in the range of 700 ° C to 1500 ° C.
- the particle size can be controlled to about 0.3 to 2 ⁇ m.
- the aggregated particles 92 in which a plurality of MgO crystal particles are agglomerated mainly confirms the effect of suppressing the “discharge delay” in the write discharge and the effect of improving the temperature dependency of the “discharge delay”.
- the agglomerated particles 92 are excellent in the initial electron emission characteristics as compared with the base film 91. Therefore, in the present embodiment, the agglomerated particles 92 are arranged as an initial electron supply unit required at the time of discharge pulse rising.
- the “discharge delay” is considered to be mainly caused by a shortage of the amount of initial electrons that are triggered from the surface of the base film 91 being discharged into the discharge space 16 at the start of discharge. Therefore, in order to contribute to the stable supply of initial electrons to the discharge space 16, the agglomerated particles 92 are dispersedly arranged on the surface of the base film 91. As a result, abundant electrons are present in the discharge space 16 at the rise of the discharge pulse, and the discharge delay can be eliminated. Therefore, such initial electron emission characteristics enable high-speed driving with good discharge response even when the PDP 1 has a high definition.
- the metal oxide aggregated particles 92 are disposed on the surface of the base film 91, in addition to the effect of mainly suppressing the “discharge delay” in the write discharge, the effect of improving the temperature dependency of the “discharge delay” is also achieved. can get.

- sample A was 90
- sample B was 87
- sample C was 85
- sample D was 81
- sample E was 82.
- Samples A to E are PDPs manufactured by a normal manufacturing method. That is, samples A to E are PDPs manufactured by a manufacturing method that does not have a reducing organic gas introduction step.
- the luminance increases by about 30%, but in the comparative example, the sustain voltage increases by about 10%.
- the PDP 1 having the base film 91 having the same configuration as the samples A to E was manufactured by the manufacturing method according to the present embodiment.
- the first temperature profile was used from the sealing step C1 to the discharge gas supply step C4.
- the sustain voltage of the PDP 1 according to the present embodiment was about 5% lower than those of the samples A to E.
- nitrogen gas is allowed to flow as an inert gas so that the inside of the discharge space 16 is in a positive pressure state through the through-hole opened in the discharge space 16, and then When sealing, it was about 5 to 7% lower than samples A to E.
- [5-2. Prototype evaluation 2] A PDP having a protective layer having a different configuration was manufactured. As shown in FIG. 10, the conditions are the case of only the base film 91 and the case where the aggregated particles 92 are arranged on the base film 91.
- the base film 91 was made of MgO and CaO. That is, it corresponds to the sample A described above.
- the discharge delay increases as the Ca concentration increases.
- the agglomerated particles 92 are disposed on the base film 91, the discharge delay can be significantly reduced. That is, even if the Ca concentration increases, the discharge delay hardly increases. Note that the method described in Japanese Patent Application Laid-Open No. 2007-48733 was used to measure the discharge delay. The measuring method will be described later.
- Prototype 1 is a PDP having only a protective layer made of MgO.
- Prototype 2 is a PDP having a protective layer made only of MgO doped with impurities such as Al and Si.
- Prototype 3 is a PDP in which only primary particles of crystal particles 92a made of MgO are dispersed on an MgO base film.
- the sample A described above was applied as the protective layer 9. That is, the protective layer 9 includes a base film 91 made of MgO and CaO, and aggregated particles 92 that are substantially uniformly distributed over the entire surface of the base film 91. Note that, in the X-ray diffraction analysis, the base film 91 has a diffraction angle indicating a peak of the (111) plane of 36.1 degrees.
- prototypes 1 to 4 were manufactured by the above-described manufacturing method.
- the first temperature profile was used for introducing and exhausting the reducing organic gas. Further, therefore, the difference between the prototypes 1 to 4 is only the structure of the protective layer 9.
- Electron emission performance and charge retention performance were measured for prototypes 1 to 4.
- the electron emission performance is a numerical value indicating that the larger the electron emission performance, the larger the amount of electron emission.
- the electron emission performance is expressed as the initial electron emission amount determined by the surface state of the discharge, the gas type and the state.
- the initial electron emission amount can be measured by a method of measuring the amount of electron current emitted from the surface by irradiating the surface with ions or an electron beam.
- a numerical value called a statistical delay time which is a measure of the likelihood of occurrence of discharge, was measured.
- a numerical value linearly corresponding to the initial electron emission amount is obtained.
- the delay time at the time of discharge is the time from the rise of the address discharge pulse until the address discharge is delayed. It is considered that the discharge delay is mainly caused by the fact that initial electrons that become a trigger when the address discharge is generated are not easily released from the surface of the protective layer into the discharge space.
- a voltage value (hereinafter referred to as a Vscn lighting voltage) applied to the scan electrode necessary for suppressing the charge emission phenomenon of the PDP was used. That is, a low Vscn lighting voltage indicates a high charge retention capability. When the Vscn lighting voltage is low, the PDP can be driven at a low voltage. Therefore, components having a small withstand voltage and capacity can be used as the power source and each electrical component. In a current product, an element having a withstand voltage of about 150 V is used as a semiconductor switching element such as a MOSFET for sequentially applying a scanning voltage to a panel.
- the Vscn lighting voltage is preferably suppressed to 120 V or less in consideration of variation due to temperature.
- the electron emission capability and the charge retention capability of the protective layer are contradictory. It is possible to improve the electron emission performance by changing the film formation conditions of the protective layer, or by forming a film by doping the protective layer with impurities such as Al, Si, and Ba. However, as a side effect, the Vscn lighting voltage also increases.
- the electron emission capability of the protective layer of prototype 3 and prototype 4 is more than eight times that of prototype 1.
- the Vscn lighting voltage is 120 V or less. Therefore, the PDPs of the prototype 3 and the prototype 4 are more useful for a PDP in which the number of scanning lines is increased due to high definition and the cell size is small. That is, the PDPs of the prototype 3 and the prototype 4 can realize a good image display at a lower voltage by satisfying both the electron emission capability and the charge retention capability.
- the top of the partition 14 may be damaged.
- the agglomerated particles 92 are present at the portion corresponding to the top of the partition wall. That is, if the number of aggregated particles 92 to be dispersed and arranged increases, the probability of breakage of the partition walls 14 increases. From this point of view, when the average particle size is increased to about 2.5 ⁇ m, the probability of partition wall breakage increases rapidly. On the other hand, if the average particle size is smaller than 2.5 ⁇ m, the probability of partition wall breakage can be kept relatively small.
- the PDP 1 having the protective layer 9 according to the present embodiment it is possible to obtain an electron emission ability having characteristics of 8 or more and a charge holding ability of Vscn lighting voltage of 120 V or less.
- the method for manufacturing PDP 1 disclosed in the present embodiment includes the following steps.
- the protective layer 9 is exposed to the reducing organic gas by introducing a gas containing the reducing organic gas into the discharge space.
- reducing organic gas is discharged from the discharge space.
- the discharge gas is sealed in the discharge space.
- Oxygen deficiency occurs in the protective layer 9 exposed to the reducing organic gas. Oxygen deficiency is considered to improve the secondary electron emission ability of the protective layer. Therefore, the PDP 1 manufactured by the manufacturing method according to the present embodiment can reduce the sustain voltage.
- the reducing organic gas is preferably a hydrocarbon-based gas that does not contain oxygen. This is because the reduction ability is enhanced by not containing oxygen.
- the reducing organic gas is preferably at least one selected from acetylene, ethylene, methylacetylene, propadiene, propylene, cyclopropane, propane and butane. This is because the reducing organic gas is easy to handle in the manufacturing process. Furthermore, it is because said reducing organic gas is easy to decompose
- a manufacturing method in which a gas containing a reducing organic gas is introduced into the discharge space after exhausting the discharge space is exemplified.
- the gas containing the reducing organic gas can be introduced into the discharge space by continuously supplying the gas containing the reducing organic gas to the discharge space without exhausting the discharge space.
- the protective layer 9 includes the metal oxide crystal particles 92 a or the aggregated particles 92 in which a plurality of metal oxide crystal particles 92 a are aggregated on the base film 91, the protective layer 9 has a high charge retention capability and a high electron emission capability. Therefore, as a whole PDP 1, high-speed driving can be realized with a low voltage even with a high-definition PDP. In addition, high-quality image display performance with reduced lighting failure can be realized.
- MgO is exemplified as the metal oxide crystal particles.
- the metal oxide crystal particles are not limited to MgO.

Abstract
Description
PDPの基本構造は、一般的な交流面放電型PDPである。図1および図2に示すように、PDP1は前面ガラス基板3などよりなる前面板2と、背面ガラス基板11などよりなる背面板10とが対向して配置されている。前面板2と背面板10とは、外周部がガラスフリットなどからなる封着材によって気密封着されている。封着されたPDP1内部の放電空間16には、ネオン(Ne)およびキセノン(Xe)などの放電ガスが53kPa(400Torr)~80kPa(600Torr)の圧力で封入されている。
図3に示すように、本実施の形態にかかるPDP1の製造方法は、前面板作製工程A1、背面板作製工程B1、フリット塗布工程B2、封着工程C1、還元性ガス導入工程C2、排気工程C3および放電ガス供給工程C4を有する。
前面板作製工程A1においては、フォトリソグラフィ法によって、前面ガラス基板3上に、走査電極4および維持電極5とブラックストライプ7とが形成される。走査電極4および維持電極5は、導電性を確保するための銀(Ag)を含む金属バス電極4b、5bを有する。また、走査電極4および維持電極5は、透明電極4a、5aを有する。金属バス電極4bは、透明電極4aに積層される。金属バス電極5bは、透明電極5aに積層される。
フォトリソグラフィ法によって、背面ガラス基板11上に、データ電極12が形成される。データ電極12の材料には、導電性を確保するための銀(Ag)と銀を結着させるためのガラスフリットと感光性樹脂と溶剤などを含むデータ電極ペーストが用いられる。まず、スクリーン印刷法などによって、データ電極ペーストが所定の厚みで背面ガラス基板11上に塗布される。次に、乾燥炉によって、データ電極ペースト中の溶剤が除去される。次に、所定のパターンのフォトマスクを介して、データ電極ペーストが露光される。次に、データ電極ペーストが現像され、データ電極パターンが形成される。最後に、焼成炉によって、データ電極パターンが所定の温度で焼成される。つまり、データ電極パターン中の感光性樹脂が除去される。また、データ電極パターン中のガラスフリットが溶融する。溶融していたガラスフリットは、焼成後に再びガラス化する。以上の工程によって、データ電極12が形成される。ここで、データ電極ペーストをスクリーン印刷する方法以外にも、スパッタ法、蒸着法などを用いることができる。
背面板作製工程B1により作製された背面板10の画像表示領域外に封着部材であるガラスフリットが塗布される。その後、ガラスフリットは、350℃程度の温度で仮焼成される。仮焼成によって、溶剤成分などが除去される。
前面板2とフリット塗布工程B1を経た背面板10とが対向配置されて周辺部が封着部材により封着される。その後、放電空間16に放電ガスが封入される。
図4に示すように、まず、封着工程C1において、温度は、室温から封着温度まで上昇する。次に、温度は、a-bの期間、封着温度に維持される。その後、温度は、b-cの期間に封着温度から排気温度に下降する。b-cの期間において、放電空間内が排気される。つまり、放電空間内は減圧状態になる。
図5に示すように、まず、封着工程C1において、温度は、室温から封着温度まで上昇する。次に、温度は、a-bの期間、封着温度に維持される。その後、温度はb-cの期間に封着温度から排気温度に下降する。温度が排気温度に維持されているc-d1の期間において、放電空間内が排気される。つまり、放電空間内は減圧状態になる。
図6に示すように、まず、封着工程C1において、温度は、室温から封着温度まで上昇する。次に、温度は、a-b1-b2の期間、封着温度に維持される。a-b1の期間に放電空間内が排気される。つまり、放電空間内は減圧状態になる。その後、温度はb2-cの期間に封着温度から排気温度に下降する。
表1に示すように、還元性有機ガスとしては、分子量が58以下の還元力の大きいCH系有機ガスが望ましい。種々の還元性有機ガスの中から選ばれる少なくとも一つが希ガスや窒素ガスなどに混合されることにより、還元性有機ガスを含むガスが製造される。
図2に示すように、本実施の形態にかかる誘電体層8は、表示電極6およびブラックストライプ7を覆う第1誘電体層81と、第1誘電体層81を覆う第2誘電体層82の少なくとも2層の構成である。
第1誘電体層81の誘電体材料は、三酸化二ビスマス(Bi2O3)を20重量%~40重量%含む。さらに、第1誘電体層81の誘電体材料は酸化カルシウム(CaO)、酸化ストロンチウム(SrO)および酸化バリウム(BaO)の群から選ばれる少なくとも1種を0.5重量%~12重量%を含む。さらに、第1誘電体層81の誘電体材料は、三酸化モリブデン(MoO3)、三酸化タングステン(WO3)、二酸化セリウム(CeO2)、二酸化マンガン(MnO2)、酸化銅(CuO)、三酸化二クロム(Cr2O3)、三酸化二コバルト(Co2O3)、二酸化七バナジウム(V2O7)および三酸化二アンチモン(Sb2O3)の群から選ばれる少なくとも1種を0.1重量%~7重量%含む。
第2誘電体層82の誘電体材料は、Bi2O3を11重量%~20重量%を含む。さらに、第2誘電体層82の誘電体材料は、CaO、SrOおよびBaOの群から選ばれる少なくとも1種を1.6重量%~21重量%含む。さらに、第2誘電体層82の誘電体材料は、MoO3、WO3、酸化セリウム(CeO2)、CuO、Cr2O3、Co2O3、V2O7、Sb2O3およびMnO2から選ばれる少なくとも1種を0.1重量%~7重量%含んでいる。
誘電体層8の膜厚は、可視光透過率を確保するために、第1誘電体層81と第2誘電体層82とを合わせて41μm以下が好ましい。第1誘電体層81におけるBi2O3の含有量は、金属バス電極4b、5bに含まれるAgとの反応を抑制するために、第2誘電体層82におけるBi2O3の含有量よりも多い。よって、第1誘電体層81の可視光透過率が第2誘電体層82の可視光透過率よりも低くなる。したがって、第1誘電体層81の膜厚は、第2誘電体層82の膜厚よりも薄いことが好ましい。
Bi2O3を含む誘電体材料にMoO3またはWO3を添加することによって、Ag2MoO4、Ag2Mo2O7、Ag2Mo4O13、Ag2WO4、Ag2W2O7、Ag2W4O13といった化合物が580℃以下で生成しやすい。本実施の形態では、誘電体層8の焼成温度が550℃~590℃であることから、焼成中に誘電体層8中に拡散した銀イオン(Ag+)は誘電体層8中のMoO3またはWO3と反応することにより、安定な化合物を生成して安定化する。すなわち、Ag+が還元されることなく安定化される。Ag+が安定化することによって、Agのコロイド化に伴う酸素の発生も少なくなる。したがって、誘電体層8中への気泡の発生も少なくなる。
保護層9は、放電を発生させるための電荷を保持する機能、および、維持放電の際に二次電子を放出する機能が求められる。電荷保持性能が向上することにより、印加電圧が低減される。二次電子放出数が増加することにより、維持放電電圧が低減される。
本実施の形態にかかる保護層9は、下地膜91と凝集粒子92とを含む。下地膜91は、少なくとも第1の金属酸化物と第2の金属酸化物とを含む。第1の金属酸化物および第2の金属酸化物は、MgO、CaO、SrOおよびBaOからなる群の中から選ばれる2種である。さらに、下地膜91は、X線回折分析において少なくとも一つのピークを有する。このピークは、第1金属酸化物のX線回折分析における第1のピークと、第2金属酸化物のX線回折分析における第2のピークとの間にある。第1のピークと第2のピークは、下地膜91のピークが示す面方位と同じ面方位を示す。
凝集粒子92は、金属酸化物であるMgOの結晶粒子92aが複数凝集したものである。凝集粒子92は、下地膜91の全面に亘って、均一に分散配置させると好ましい。PDP1内における、放電電圧のばらつきが減少するからである。
凝集粒子92とは、所定の一次粒径の結晶粒子92aが凝集またはネッキングした状態のものである。すなわち、固体として大きな結合力を持って結合しているのではなく、静電気やファンデルワールス力などによって複数の一次粒子が集合体の体をなしているもので、超音波などの外的刺激により、その一部または全部が一次粒子の状態になる程度で結合しているものである。図9に示すように、凝集粒子92の粒径としては、約1μm程度のもので、結晶粒子92aとしては、14面体や12面体などの7面以上の面を持つ多面体形状を有するのが望ましい。
[5-1.試作評価1]
下地膜の構成が異なる複数のPDPが作製された。PDPには60kPaのXe,Ne混合ガス(Xe15%)が封入された。サンプルAは、MgOとCaOによって構成されている。サンプルBは、MgOとSrOによって構成されている。サンプルCは、MgOとBaOによって構成されている。サンプルDは、MgO、CaOおよびSrOによって構成されている。サンプルEはMgO、CaOおよびBaOによって構成されている。また、比較例は、MgO単体によって構成されている。
構成の異なる保護層を有するPDPが試作された。条件は、図10に示すように、下地膜91のみの場合と、下地膜91上に凝集粒子92を配置した場合である。下地膜91は、MgOとCaOとにより形成された。つまり、前述のサンプルAに相当する。下地膜91のみの場合はCa濃度の増加とともに放電遅れが大きくなる。一方、下地膜91上に凝集粒子92を配置した場合は、放電遅れを大幅に小さくすることができた。つまり、Ca濃度が増加しても放電遅れはほとんど増大しない。なお、放電遅れの測定には、特開2007-48733号公報に記載されている方法が用いられた。測定方法については、後に説明される。
構成の異なる保護層を有するPDPが試作された。
次に、凝集粒子92の粒径について詳細に説明される。なお、凝集粒子92の平均粒径は、凝集粒子92をSEM観察することにより測長された。
本実施の形態に開示されたPDP1の製造方法は、以下の工程を備える。還元性有機ガスを含むガスを放電空間に導入することにより、保護層9を還元性有機ガスに曝す。次に、還元性有機ガスを放電空間から排出する。次に、放電ガスを放電空間に封入する。
