ABSTRACT:
An electro-optical device includes pixel regions arranged at intersections of a plurality of data lines and a plurality of scanning lines on an element substrate. A sensor element, a sensor signal line for outputting a signal from the sensor element, a common wiring line, and a capacitive-coupling-operation bidirectional diode element are disposed at an end of a region on the element substrate in which the pixel regions are arranged. The capacitive-coupling-operation bidirectional diode element includes two capacitive-coupling-operation diode elements each including a semiconductor element including a source electrode, a drain electrode, a semiconductor layer having a channel region, and a gate electrode facing the channel region with a gate insulating film disposed therebetween, and a capacitor element arranged between one of the source electrode and the drain electrode and the gate electrode.
