1. A display device comprising a display portion,
wherein the display portion comprises a light-receiving element, a first light-emitting element, and a second light-emitting element,
wherein the light-receiving element comprises a first pixel electrode, a first light-emitting layer, an active layer, and a common electrode,
wherein the first light-emitting layer and the active layer are positioned between the first pixel electrode and the common electrode,
wherein the first light-emitting element comprises a second pixel electrode, the first light-emitting layer, the active layer, and the common electrode,
wherein the first light-emitting layer and the active layer are positioned between the second pixel electrode and the common electrode,
wherein the second light-emitting element comprises a third pixel electrode, a second light-emitting layer, and the common electrode,
wherein the second light-emitting layer is positioned between the third pixel electrode and the common electrode,
wherein the first light-emitting layer emits light of a first color, and
wherein the active layer comprises an organic compound which absorbs light with a wavelength shorter than a wavelength of the light of the first color.
