Abstract: A display device includes a base layer, and a pixel layer disposed on the base layer. The pixel layer includes reference pixel units and photo-sensing elements. Each of the reference pixel units includes a first light-emitting element, a second light-emitting element, and a third light-emitting element. Each of the photo-sensing elements is interposed between two second light-emitting elements adjacent to each other in a first direction, and at least one of the first light-emitting element or the third light-emitting element includes a plurality of sub-light-emitting elements electrically connected to each other.
