Abstract

A display device includes a circuit layer and an element layer including a light-emitting element, a light sensing element, and an element defining layer. The light-emitting element includes a pixel anode electrode, a pixel hole injection layer disposed on the pixel anode electrode, an emissive layer disposed on the pixel hole injection layer, and a pixel cathode electrode disposed on the emissive layer. The light sensing element includes a sensing anode electrode, a sensing hole injection layer disposed on the sensing anode electrode, a photoelectric conversion layer disposed on the sensing hole injection layer, and a sensing cathode electrode disposed on the photoelectric conversion layer. The pixel hole injection layer and the sensing hole injection layer are electrically insulated from each other, and the pixel cathode electrode and the sensing cathode electrode are electrically connected with each other.
