Abstract

A display device with an image pickup function includes: a plurality of pixel signal lines each supplied with a pixel signal; a plurality of display pixels each performing a display operation based on the pixel signal; and a plurality of image pickup elements each including a photo-detector and a capacitor, the photo-detector generating a current of a magnitude corresponding to a photo-detection amount, the capacitor performing a discharging operation which follows a charging operation with the current from the photo-detector to output a charged voltage for a read operation. In the display device, a voltage level of the pixel signal line during the discharging operation is equal to a voltage level of the pixel signal line during the reading operation.
