Abstract
A liquid crystal display device contains a coordinate input device on the front side of a liquid crystal display unit. The coordinate input device is of a resistive contact type and includes a first light-transmitting substrate, and a second light-transmitting substrate having flexibility, which are arranged to face each other with a void space therebetween. A first light-transmitting electrode layer is formed on the inner side of the first light-transmitting substrate. A second light-transmitting electrode layer is formed on the inner side of the second light-transmitting substrate. The first light-transmitting substrate is different in thickness at its central portion and at its peripheral portion.
