发明名称 COORDINATE INPUT DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE AND ELECTRONIC APPARATUS COMPRISING THE SAME
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a coordinate input device, and a liquid crystal display device and an electronic apparatus comprising the coordinate input device, capable of preventing a change in cell gap of a liquid crystal display unit placed in the lower part of the coordinate input device due to pressing force by the pressing operation of an indicating body at the time of inputting the coordinates. <P>SOLUTION: The coordinate input device is of a resistive contact type and includes a first light-transmitting substrate 32 and a second light-transmitting substrate 31 having flexibility, which are arranged to face each other with a void space therebetween. A first light-transmitting electrode layer 33 is formed on the inner side of the first light-transmitting substrate 32. A second light-transmitting electrode layer 34 is formed on the inner side of the second light-transmitting substrate 31. The first light-transmitting substrate 32 is different in thickness at its central portion 32a and at its peripheral portion 32b. The liquid crystal display device 10 contains the coordinate input device 30 on the front side of the liquid crystal display unit 20. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p>
