1. A display device comprising:
a light-emitting element;
a light-receiving element;
a first transistor;
a second transistor;
a first conductive layer; and
a second conductive layer,
wherein the light-emitting element comprises a first pixel electrode, a light-emitting layer, and a common electrode,
wherein the light-receiving element comprises a second pixel electrode, an active layer, and the common electrode,
wherein the first pixel electrode and the second pixel electrode are on the same plane,
wherein the common electrode comprises a portion overlapping with the first pixel electrode with the light-emitting layer therebetween, and a portion overlapping with the second pixel electrode with the active layer therebetween,
wherein the light-receiving element is configured to receive light emitted from the light-emitting element,
wherein the first pixel electrode is provided over a channel formation region of the first transistor,
wherein part of the second pixel electrode of the light-receiving element directly overlaps with a channel formation region of the second transistor,
wherein the first conductive layer and the second conductive layer are above the common electrode, and
wherein the first conductive layer is provided between the light-emitting element and the light-receiving element in a plan view of the display device.
