Liquid crystal display device
First Claim
1. A liquid crystal display device, comprising:
- a first substrate;
a second substrate;
a liquid crystal layer formed between said first substrate and said second substrate;
a display function region formed between the first substrate and the second substrate, the display function region having an image display function, and wherein a video signal is supplied from a signal line via a transistor in each pixel and a display pixel electrode is formed on the first substrate;
at least one short pixel electrode is formed on the second substrate such that by pressing on either the first substrate or the second substrate, a short is caused for two adjacent pixel electrodes via the short pixel electrode, and a sensor drive circuit detects a signal level change based on contact with the short pixel electrode.

Abstract
An embodiment of the invention provides a liquid crystal display device, including a first substrate; a second substrate; a liquid crystal layer formed between the first substrate and the second substrate; a first sensor electrode formed on the first substrate; a second sensor electrode formed on the second substrate, and disposed so as to be adapted to contact the plurality of first sensor electrodes close to one another by pressing from a side of either the first substrate or the second substrate; and a sensor drive circuit for applying a voltage to a first wiring electrically connected to one of the plurality of first sensor electrodes which the second sensor electrode is adapted to contact by the pressing, and detecting a change in potential of a second wiring electrically connected to another one of the plurality of first sensor electrodes.
