Light-emitting apparatus

Abstract

To provide a display apparatus having a function of emitting visible light and infrared light and a function of detecting light.SOLUTION: A display apparatus has a first light-emitting device, a second light-emitting device, and a light-receiving device in a display part. The first light-emitting device has a first pixel electrode, a first optical adjustment layer, a first light-emitting layer, a second light-emitting layer, and a common electrode. The second light-emitting device has a second pixel electrode, a second optical adjustment layer, a first light-emitting layer, a second light-emitting layer, and a common electrode. The light-receiving device has a third pixel electrode, an active layer, and a common electrode. The active layer has an organic compound. The first light-emitting device radiates infrared light emitted from the first light-emitting layer. The second light-emitting device radiates visible light emitted from the second light-emitting layer. The light-receiving device has a function of absolving at least a part of the visible light and the infrared light.SELECTED DRAWING: Figure 1
