Abstract

A display device includes a substrate; and a plurality of unit pixels disposed on the substrate and including sub-pixels and photo-sensing pixels. Each of the sub-pixels includes a light emitting element and a light emitting area from which light is emitted. Each of the photo-sensing pixels includes a light receiving area and a light receiving element disposed therein and outputting a sensing signal corresponding to a degree of sensed light. The light emitting area and the light receiving area are spaced apart from each other on the substrate. The light emitting area and the light receiving area each have a polygonal shape. Aa shape of the light emitting area is different from a shape of the light receiving area.
