Abstract

A display apparatus having a photosensing function is provided. The display apparatus includes a first pixel circuit and a second pixel circuit. The first pixel circuit includes a light-receiving device, a first transistor, and a second transistor. The second pixel circuit includes a light-emitting device. The light-receiving device includes a first pixel electrode, an active layer, and a common electrode. The light-emitting device includes a second pixel electrode, a light-emitting layer, and the common electrode. The active layer is positioned over the first pixel electrode and includes a first organic compound. The light-emitting layer is positioned over the second pixel electrode and includes a second organic compound different from the first organic compound. The common electrode includes a portion overlapping with the first pixel electrode with the active layer therebetween and a portion overlapping with the second pixel electrode with the light-emitting layer therebetween. The first transistor includes low-temperature polysilicon as a semiconductor layer and the second transistor includes a metal oxide as a semiconductor layer.
