DISPLAY DEVICE
First Claim
1. A display device, comprising:
- a first substrate having thereon a plurality of pixel electrodes and a first switching element connected to said pixel electrode in each of a plurality of pixels;
a second substrate placed opposite to the first substrate;
a display medium layer disposed between the first substrate and the second substrate;
a plurality of first electrodes formed on the first substrate;
a plurality of second electrodes formed on the first substrate, the second electrodes being electrically insulated from each of the first electrodes and placed side by side with the first electrodes, respectively;
a plurality of conductive layers arranged on the second substrate so as to respectively face pairs of the first electrode and the second electrode placed side by side with each other, the plurality of conductive layers being formed to be electrically insulated from each other;
a plurality of first wiring lines and a plurality of second wiring lines formed on the first substrate;
a voltage supply portion for applying a voltage to the first electrodes through the first wiring lines;
a detection portion that detects a voltage applied to the first electrode by the voltage supply portion through the conductive layer, the second electrode, and the second wiring line as a result of the conductive layer making contact with the first electrode and the second electrode when the first substrate or the second substrate is pressed; and
a second switching element interposed at least one of between the first electrode and the first wiring line and between the second electrode placed side by side with said first electrode and the second wiring line.

Abstract
A display device includes: a first electrode and a second electrode which are arranged side by side with each other on a first substrate; a conductive layer which is arranged on a second substrate so as to face the first electrode and the second electrode; a voltage supply portion for applying a voltage to the first electrode through a first wiring line; a detection portion for detecting the voltage that is applied to the first electrode through the conductive layer, the second electrode, and a second wiring line as a result of the conductive layer making contact with the first electrode and the second electrode; and a second switching element which is interposed at least one of between the first electrode and the first wiring line and between the second electrode and the second wiring line.
