Abstract
The present invention relates to a display device including a photosensor in a pixel region. The photosensor of the present invention includes a diode (D) that receives incident light, reset signal wiring (RST) that supplies a reset signal, readout signal wiring (RWS) that supplies a readout signal, a storage node (INT) whose potential changes in accordance with the amount of light received by the photodetection element in a sensing period, the sensing period being from when the reset signal is supplied until when the readout signal is supplied, an amplification element (C) that amplifies the potential of the storage node in accordance with the readout signal, and a sensor switching element (M) for reading out the potential amplified by the amplification element to output wiring (OUT) as sensor circuit output.
