1. A display device comprising:
a light-emitting and light-receiving element over a first substrate; and
a color filter above the light-emitting and light-receiving element,
wherein the light-emitting and light-receiving element comprises a light-emitting and light-receiving region configured to emit light of a first color and receive light of a second color,
wherein the light-emitting and light-receiving element includes at least an EL layer and a photoelectric conversion layer between a pixel electrode and a common electrode,
wherein the color filter is configured to transmit the light of the first color and block the light of the second color,
wherein the color filter comprises an opening over the light-emitting and light-receiving region, and
wherein in a plan view, the light-emitting and light-receiving region comprises a portion located inside the opening.
