- a transparent electrode having an uppermost layer is provided.
- the color filter substrate 100 includes a transparent substrate 2, a color filter 3 formed on the transparent substrate 2, and a common electrode as basic components. Between the color filter substrate 100 and the TFT substrate 220, in order to make the layer thickness of the liquid crystal space uniform over the entire screen, a cylindrical spacer is placed in an opaque place where the black matrix 4-1 of the color filter substrate is placed. S 4—2 is arranged.
- the light emitted from the knocklight is linearly polarized by a polarizing plate (not shown) provided on the TFT substrate, and the polarization characteristics are controlled while passing through the liquid crystal 210 (that is, the polarization characteristics change or change). Not) or is blocked or transmitted by the polarizing plate provided on the color filter substrate 100.
- FIG. 1 schematically shows typical components of the color filter substrate in the liquid crystal display.
- the display screen is color filter red (R) 3-1, It is composed of a plurality of pixels in which blue (B) 3-2 and green (G) 3-3 are formed.
- the spacer 42 is formed on the black matrix 4-1 by the process of exposing and etching the photosensitive resin. Further, the height 9 of the spacer 42 is about 4111, and it is formed at the same height so that no color irregularity occurs in the place where the liquid crystal is sealed.
- the color ink is applied in a thickness of 1 to 3 m.
- the physical properties such as the viscosity and the curing speed of the color ink are applied.
- protrusions 8 may be formed in the filter pixel portion. This is a protrusion-like defect.
- the height 10 of this protrusion is about 10 m and the diameter of the cylinder is about 20 Hm to 100 nm.
- the distance between the TFT substrate that is oppositely disposed in a pair with the color filter substrate is not determined by the height 9 of the spacer 42, but is a defect. It is determined by the height 10 of a certain protrusion 8. Therefore, the layer thickness of the liquid crystal space varies depending on the position, color unevenness occurs, and the liquid crystal display cell becomes defective.

- the transparent substrate of the color filter is once removed, and then the color or black ink is filled and cured, so that at least two steps of removal and filling are required. There is a disadvantage that it becomes important.
- the present invention is a method of manufacturing a substrate having a flat surface by removing protrusions protruding from the surface of the substrate, and a short processing depth of focus focused beam by a high NA focusing lens is applied to the substrate surface
- a method of manufacturing a substrate including a step of removing a protrusion at a position on the surface of the substrate so that the protrusion is below the fluence at the same time as the protrusion is irradiated with a fluence necessary for the removal of the protrusion.
- the working efficiency can be improved by scanning the beam parallel to the substrate surface.
- the short focal depth focused beam is preferably a fundamental harmonic such as the second harmonic, the third harmonic, or the fourth harmonic.
- the position of the beam waist should be at or near the substrate surface.
- the present invention can be efficiently implemented by detecting the planar shape of the protrusion and scanning only a certain range including the planar shape when the planar shape is detected. At that time, the focused light beam or the image of the aperture may be scanned.
- the wavelength of the laser used is preferably about 560 to 390 nm, and more preferably 390 nm or less. This is because the material of the color filter that becomes the protrusion is mainly resin, so it has a relatively high absorption characteristic from the visible to the ultraviolet region, and therefore only a small part of the surface layer irradiated with the laser is present. This is because it is easily removed. Further, it is preferable Bruno pulse width of the laser is less than 1 X 10- 12 seconds. Further, if the substrate force S color filter substrate is used, a color filter substrate from which protrusions formed by ink are appropriately removed can be obtained.
- the projection higher than the spacer is relatively scanned with the short processing depth of focus focused beam by the high NA condenser lens in the direction parallel to the substrate surface.
- the present invention also provides a laser light generating means, a condensing lens that converts the laser light generated by the laser light generating means into a convergent beam, and a color filter that is the object to be processed.
- Relative moving means that performs relative scanning in a direction parallel to the surface of the filter substrate is provided, and projections higher than the spacer of the color filter are formed by irradiating the convergence beam while performing relative scanning.
- the present invention solves the above-mentioned problems by providing a color filter protrusion correcting device to be removed.
- a stage as a relative moving means for the convergent beam, it is possible to use a Ganolevano mirror optical system.
- the position of the protrusion is measured in the inspection process, and then removed with a short focal depth condensing laser beam at the next! / It becomes possible to process to the height of.
- the short pulse of picoseconds or less and the short pulse in the infrared region are converted into an ultraviolet laser, and the ultraviolet short pulse is condensed by a high NA condenser lens.
- the projection within the processing focus is corrected by removing. It is possible to simplify the correction process by removing the portion above the predetermined height while leaving the protrusions on the color filter substrate to the predetermined height.
- a space including a tip of a protrusion that causes a defective product can be obtained simply by irradiating a laser beam onto a protrusion-like defect generated in the manufacturing process. Since the part higher than the bottom can be easily removed, the product yield can be improved and the product cost can be reduced. Further, in the method of correcting the protrusions by the conventional laser method, after the protrusions are completely removed to the substrate, a force that requires a step of correcting the color ink by filling the removed portions as a separate process is required. There is an advantage that correction can be completed by removing only the protrusion.
- the removal is performed at a high power density of a short pulse, the removed matter can be scattered by being finely vaporized, and if the suction nozzle is placed close to the protrusion of the processing point, it can be easily made into a gaseous body. And sucking bow I can be processed.
- FIG. 1 is a schematic cross-sectional arrangement view of a color filter substrate, a TFT substrate, and a liquid crystal sealing space.
- FIG. 2 A schematic diagram of a cross-sectional arrangement of a color filter substrate on which color filter protrusions and spacers are arranged.
- FIG. 3 A diagram showing a laser focusing optical system for cutting a protrusion and an installation relationship at the time of processing the protrusion for carrying out the present invention.
- FIG. 5 is a diagram in which a simulated protrusion is partially cut according to the present invention.
- Beam waist position 24 XY stage
- a typical component of the color filter substrate shown in FIG. 2 is a processing target according to the present invention.
- the color filter is provided with a transparent electrode (not shown) and an alignment film on the transparent electrode, but it is not shown here because it is not related to the processing method of the invention.
- the opaque part 4-1 of the black matrix is formed by patterning a deposited film such as chromium on the transparent substrate 2 constituting the color filter, and red, green, Blue color filters 3-1, 3-2 and 3-3 are provided.
- a spacer 4-2 that determines a spatial distance between the color filter substrate 100 and the TFT substrate 220 is provided in a portion of the black matrix 4-1 that does not transmit light. This height 9 is about 4 H m.
- the protrusions 8 formed in the color filter manufacturing process for applying the correction method of the present invention may have a height 10 ranging from about 10 m to 100 ⁇ m. If the protrusion with such a height is assembled as it is as a liquid crystal substrate cell, the thickness of the space for enclosing the liquid crystal 210 varies depending on the location. For this reason, color unevenness occurs in the liquid crystal display substrate, and a practical display device cannot be obtained. Thus the height of the projection 8 is required to be kept small Tomosupesa 4 to 2 height 9 below.
- a cut surface is generally formed along the optical axis direction of the laser beam.
- This departure Akira controls the power density in the spatial axial direction of the laser beam to form a machined surface perpendicular to the optical axis of the laser beam.
- machining focal length is considered equivalent to the optical focal length, the range is given by ⁇ / ⁇ ⁇ 2.
- NA is the numerical aperture of the lens.
- the Caloe focal length is inversely proportional to the square of NA. This means that the processing range in the optical axis direction can be limited to a small range by using a short-focus large-aperture lens.
- the processing focal length is 0.9 m. Therefore, when such a high NA condensing lens is used, the processing range can be controlled in the optical axis direction with this processing focal depth.
- the flatness of the processed surface is a force S that changes depending on the overlap ratio of the scanning spot, and about 50% is sufficient for practical use when cutting out the protrusions of the color filter.
- FIG. 3 shows an arrangement relationship between the above-described optical system and projections of a color filter that is a processing object.
- a pulse of 390 nm wavelength is obtained by converting the wavelength of a 1560 nm femtosecond laser from a mode-locked femtosecond laser generator using an optical fiber to half the wavelength using a nonlinear optical crystal. Amplified by, and converted to the near-infrared wavelength with a nonlinear optical crystal to obtain an ultraviolet short pulse output with a wavelength of 390 nm.
- this nozzle is incident on the high NA condensing lens 18 as a beam 19 in the direction of the arrow 20, and the convergent beam 17 exiting the condensing lens is irradiated toward the projection 8.
- the convergent beam 17 forms a focused beam waist 16.
- the processing focal depth in the vicinity of the beam waist 16 can be reduced to a sufficiently small value of 1 ⁇ m or less.
- the beam waist position 22 is set to a level that is approximately 13 deeper than the processing focal depth 13 above the cut-off position level 14 of the color filter.
- the beam scanning shown in FIG. 4 is performed.
- An XY stage 24 is mounted on a stage base 25, and a projection 23 is disposed thereon.
- the XY stage 24 is scanned in a plane perpendicular to the laser beam optical axis by a zigzag locus 26.
- This scanning trajectory runs to the area outside the protrusion. Even if you hesitate, this part will not be adversely affected.
- the projection 8 shown in FIG. 3 comes into the processing focus of the laser beam by such beam scanning, the projection in the processing focus is removed.
- the removed protrusion is indicated by a broken line 8-1.
- the remaining protruding portion 8-2 is removed, and as a result, the protruding portion is cut off from the cut surface 14.
- a method of moving the beam in a zigzag shape as shown in FIG. 4 using a galvanometer mirror may be used.
- the laser beam used was a wavelength of 390 nm, which is the second harmonic of a Ti: Sa (titanium sapphire) laser that oscillates at 780 nm as the fundamental wave.
- Pulse repetition rate 1000 Hz
- Bruno Bruno less energy employing 5 nJ
- pulse width 200 fs
- the beam quality M 2 X-direction 1.63
- Y-direction 1.62 lenses may NA is 0.7 to (manufactured by Mitutoyo M Plan MR 100 X HR)
- scanning speed 10 m / s
- scanning pitch 1 m
- energy irradiation fluence 0.6 J m 2
- artificially made of the same material as the color filter shown in the photograph in Fig. 5 In order to cut out the upper half of the simulated protrusion 30, a beam was scanned from the lower side of the photo to the left and right, and about half were cut off.
- the step 28 between the excision surface 27 and the top 29 of the simulated projection is formed by excision, and the surface roughness of the excision surface varies depending on the overlapping rate of the focused spots at the time of irradiation, that is, the overlap rate. In the case of 50%, the roughness was 60 nm. This surface roughness is sufficiently flat for use as a color filter. It can be seen that sufficient processing accuracy can be obtained because the height of the protrusions should be cut to a level lower than the spacer. In the method of the present invention, since a laser beam having a narrow pulse width is used, there is no denaturation or the like with less thermal shock at the processing point. In addition, since the portion irradiated with the laser light is turned into plasma, there is almost no effect on the colorant.
- the fundamental wave of the titanium sapphire laser is not necessarily 780 nm, and the wavelength can be adjusted between about 700 and 900 ⁇ m. Therefore, the second harmonic is about 350 to 450 nm, and the third harmonic is about 233 to 300 nm. It is also possible to use the second or third harmonic of a Yb (ytterbium) fiber laser whose fundamental wave is about 980 to 1120 nm.
- Nonlinear optical crystals for obtaining harmonics include LBO (lithium triborate), BBO (barium baud rate) is used.
- the 3rd harmonic (355nm) and 4th harmonic (266nm) can also be used, and the 3rd harmonic, especially the 4th harmonic, which is an ultraviolet region with high absorption into the material, has a remarkable effect.
- the embodiment described above can also be applied to the case where the force described for the color filter of the liquid crystal display device and other protrusions of the display device are removed.
- the color display method can be used in the process of correcting protrusion defects in color filters used for organic EL color display.
- a spacer is not necessary, but it is conceivable that the protrusion may cause a defect.
- the method for removing protrusions of the present invention can also be used to remove burrs generated during machining.
- the position of the laser beam waist is set at the top of the main body with a high NA condensing lens, only the protrusion is cut off, and the power density is adjusted in the optical axis direction by the short processing depth of focus so that the main body surface remains intact. Set using the shallow depth of processing focus and cut only the burr.
