A display apparatus capable of performing image capturing with high sensitivity is provided. The display apparatus includes a light-emitting element including a light-emitting layer, and a light-receiving element including a photoelectric conversion layer. A transflective electrode is provided over the light-emitting layer, and a transparent electrode is provided over the photoelectric conversion layer. With a structure where the transflective electrode does not overlap the photoelectric conversion layer, a reduction in light-receiving sensitivity of the light-receiving element can be prevented while a microcavity structure is used for the light-emitting element. Thus, the display apparatus can emit light with high color purity and perform image capturing with high sensitivity.
