Indication device

Abstract

To improve the resolution of display devices with light detection capabilities. [Solution] A display device having light-emitting devices 47B and 47G and a light-receiving device 47R, wherein the light-emitting devices 47B and 47G have a first pixel electrode 191, a first light-emitting layer 193B and 193G, and a common electrode 115, and the light-receiving device 47R has a second pixel electrode 191, a second light-emitting layer 193R, an active layer 183 of an organic compound, and a common electrode 115, wherein the first light-emitting layers 193B and 193G, and the second light-emitting layer 193R and the active layer 183 are located between the first pixel electrode 191 and the common electrode 115, one light-emitting device 47B emits light of a first color, and the light-receiving device 47R emits light of a second color and receives light of the first color. By having the light-receiving device 47R serve as both a light-emitting device and a light-receiving device, a light-receiving function can be added without increasing the number of subpixels. It is possible.

Claims
