Abstract
A display device includes a plurality of pixels, each of which includes a light emitting element and a pixel driving circuit and a plurality of sensors, each of which includes a light receiving element and a sensor driving circuit. A sensor driving circuit included in at least one of sensors includes a reset transistor configured to output a reset signal to a first sensing node in response to a reset control signal, an amplification transistor connected to first and second sensing nodes and configured to receive a sensor driving voltage, a first output transistor connected between the second sensing node and a readout line and configured to receive a first output control signal, and a second output transistor connected between the second sensing node and the readout line and configured to receive a second output control signal.
