Light-Emitting Device, Light-Emitting Apparatus, Light-Emitting Module, Lighting Device, Display Apparatus, Display Module, and Electronic Device

A display apparatus comprising a display portion,

• wherein the display portion comprises a first light-emitting device, a second light-emitting device, and a light-receiving device,
• wherein the first light-emitting device is configured to emit both visible light and infrared light,
• wherein the second light-emitting device is configured to emit visible light,
• wherein the light-receiving device is configured to absorb at least part of visible light and infrared light,
• wherein the first light-emitting device comprises a first pixel electrode, a first light-emitting layer, a second light-emitting layer, and a common electrode,
• wherein the first light-emitting layer and the second light-emitting layer are each positioned between the first pixel electrode and the common electrode,
• wherein the second light-emitting device comprises a second pixel electrode, a third light-emitting layer, and the common electrode,
• wherein the third light-emitting layer is positioned between the second pixel electrode and the common electrode,
• wherein the light-receiving device comprises a third pixel electrode, an active layer, and the common electrode,
• wherein the active layer is positioned between the third pixel electrode and the common electrode,
• wherein the first light-emitting layer comprises a light-emitting material emitting infrared light,
• wherein the second light-emitting layer and the third light-emitting layer each comprise a light-emitting material emitting visible light,
• wherein a wavelength of the visible light emitted from the light-emitting material in the second light-emitting layer is different from a wavelength of the visible light emitted from the light-emitting material in the third light-emitting layer, and
• wherein the active layer comprises an organic compound.
