題点を有していた。However, in the past, these devices required a cabinet with a closed exterior, and there was a limit to their ability to be made ultra-thin. Furthermore, in an attempt to reduce the thickness of the cabinet, instead of using a hard or flexible board, a proposal has been made in which the cabinet itself is used as a circuit board (Japanese Patent Publication No. 56-27147). In particular, this product focuses on the fact that the cabinets of desktop computers, etc. are made of insulators such as plastic, and has several stages of key electrodes and key wiring conductors on the inside of the cabinet, omitting a printed circuit board, and a key power section. Although it has a thin structure, it has problems such as poor mass production and an inability to reduce the price sufficiently.

質14を注入し密閉する。Further, in the lower flexible substrate 1, the display window 3 and the filter 5 for protecting the solar cells need to be transparent, so it is preferable to use a transparent member such as polyester. Further, in order to prevent the inside from being seen, the outside of the upper flexible substrate 1 except for the display window 3 and filter 5 can be colored by printing or the like, and the key symbol 2 can also be printed at the same time. On the other hand, a display common electrode 8. Terminal 7 for attaching an electronic component 129, for example, an LSi chip. Key contact 6. The key wiring 6' is made of indium and is formed in the same manner as the display segment electrode 4 of the partially flexible substrate 1, and a seal portion I is formed at the peripheral edge of the lower flexible substrate 10 and the liquid crystal material storage area. do. A solar cell 9 such as an amorphous solar cell is also formed on an electrode made of indium by glow discharge. Note that a method of attaching a separate solar battery cell may also be used. The electronic component 12 such as an LSi chip can be electrically connected to the electronic component mounting terminal 7 on the lower flexible substrate 10 by pressure bonding using a hot melt adhesive or conductive rubber. In addition,
Although the seal portion 11 is formed on the lower flexible substrate 10, it can be formed on the lower flexible substrate 1 in a similar manner, for example. Then, the upper or lower flexible substrates are tightly connected to each other via the seal portion 11 formed on the upper or lower flexible substrate. Thereafter, a liquid crystal material 14 is injected into the display section and the display section is sealed.
