Abstract:
1. An electro-optical device comprising: an element substrate, wherein a plurality of data lines, a plurality of scanning lines, and a plurality of pixel transistors connected to the scanning lines and the data lines are disposed on the element substrate, wherein 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 on the element substrate, the capacitive-coupling-operation bidirectional diode element including two capacitive-coupling-operation diode elements each including the sensor signal line is electrically connected to the common wiring line via the capacitive-coupling-operation bidirectional diode element, and a control wiring line for supplying a gate voltage setting the semiconductor elements of the capacitive-coupling-operation bidirectional diode element to be in a non-conducting state is disposed for the capacitive-coupling-operation bidirectional diode element.
