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. The sensor driving circuit includes a first reset transistor, a second reset transistor, a sensing capacitor, an amplification transistor, and an output transistor. The first reset transistor includes a first electrode receiving a reset voltage, a second electrode connected to a first sensing node, and a third electrode receiving a reset control signal. The second reset transistor includes a first electrode receiving the reset voltage, a second electrode connected to a second sensing node, and a third electrode receiving the reset control signal. The sensing capacitor is positioned between the first sensing node and the second sensing node.
