Abstract
A display device may include first to third semiconductor light-emitting devices in each of a plurality of pixels, a sensing element, and a circuit block in each of the plurality of pixels. The sensing element may include a fourth semiconductor light-emitting device. The first to third semiconductor light-emitting devices may emit light during the first section by a power source having a forward bias. The fourth semiconductor light-emitting device may be light-received by a power source having a reverse bias.
