た部分が最も大きく距離が離れるほど小さくなる。FIG. 1 shows an embodiment in which a transparent key is superimposed on the upper surface of the liquid crystal display section, and the liquid crystal display key is -. Reference numeral 1 denotes an upper transparent film, and transparent electrodes X, to X4 for performing key operations are wired to the upper transparent film 1. Reference numeral 2 denotes a lower transparent film, and transparent electrodes y1 to y4 are wired to the lower transparent film 2 for performing key manual operations. 3 is a spacer, and the upper transparent film 1 and the lower transparent film 2 are adhered to this spacer 3 to form a keyed portion A. The liquid crystal display part B is on the upper glass 4. Lower glass 5. The transparent key is formed of an upper polarizing plate 6° and a reflecting plate 7 with a polarizing plate, and the lower surface of the lower transparent film 2 of the negative portion A and the upper surface of the upper polarizing plate 6 of the liquid crystal display portion B are adhered to form the liquid crystal display key. A date is formed. Now, when the part of the liquid crystal display key with the characters A-P displayed in the - code is pressed with a finger or the like, the upper transparent film 1 of the transparent key date part A is pressed and comes into contact with the lower transparent film 2. The touched part is determined using XI to x4 and y1 to y4, and the pressed key contact information is input. At this time, liquid crystal display section B
The upper glass 4 is also pressed down at the same time, and the distance between the liquid crystal layer between the upper glass 4 and the lower lath 5 changes, causing the pressed character part and peripheral part of the displayed characters A-P to change. A domain occurs. This domain is largest at the pressed part and becomes smaller as the distance increases.

When the press information 14 from the transparent key date section 13 is input (Stella 7° 21), the characters A-P, etc. displayed on the liquid crystal display section 10 are changed according to the press information to prevent the domain from occurring. Driving to the display driver part 11 is stopped in order to be prohibited for a certain period of time. (Step 23.24)
The CPU 12 monitors the press information from the key date section 13. When the press information disappears (Step 3
1) Display information is output to the display driver part 11 in order to resume displaying on the liquid crystal display unit 10 which has been prohibited 17. (Step 20) When erasing the display screen metal here, the entire surface is erased in step 24, but since domains often occur only around the pressed key contact area, the area around the pressed key contact area is The occurrence of domains can also be prevented by erasing the characters (Stella f23). Instead of restarting the display on the first screen immediately after the switch press information disappears, the erasing time may be extended until the stress on the glass is completely eliminated.
