Abstract

The resolution of a display apparatus having a light detection function is increased. The display apparatus includes a light-emitting device and a light-emitting and light-receiving device. The light-emitting device includes a first pixel electrode, a first light-emitting layer, and a common electrode; the light-emitting and light-receiving device includes a second pixel electrode, a second light-emitting layer, an active layer, and the common electrode; the active layer includes an organic compound; the first light-emitting layer is positioned between the first pixel electrode and the common electrode; the second light-emitting layer and the active layer are each positioned between the second pixel electrode and the common electrode; the light-emitting device has a function of emitting light of a first color; and the light-emitting and light-receiving device has a function of emitting light of a second color and a function of receiving light of the first color. The light-emitting and light-receiving device functions as both a light-emitting device and a light-receiving device, whereby a pixel can have a light-receiving function without an increase in the number of subpixels included in the pixel. Furthermore, the pixel can be provided with a light-receiving function without a reduction in the resolution of the display apparatus or a reduction in the aperture ratio of each subpixel.
