Display system, display device, and light-emitting apparatus

A display device comprising:

• a display portion comprising:
• a plurality of display elements emitting visible light;
• and
• a plurality of light-receiving elements receiving visible light,
• wherein the plurality of display elements are arranged in a matrix,
• wherein the plurality of light-receiving elements are arranged in a matrix,
• wherein the display element comprises a first pixel electrode, a first common layer, a light-emitting layer, a second common layer, and a common electrode,
• wherein the light-receiving element comprises a second pixel electrode, the first common layer, an active layer, the second common layer, and the common electrode,
• wherein the light-emitting layer comprises a first organic compound,
• wherein the active layer comprises a second organic compound,
• wherein the first pixel electrode and the second pixel electrode are provided on the same plane,
• wherein the common electrode comprises a region overlapping with the first pixel electrode with the first common layer, the light-emitting layer, and the second common layer therebetween and a region overlapping with the second pixel electrode with the first common layer, the active layer, and the second common layer therebetween,
• wherein the first common layer is configured to transport or inject a hole,
• wherein the second common layer is configured to transport or inject an electron,
• wherein a partition is provided between the first pixel electrode and the second pixel electrode, and
• wherein the display device comprises a region where the first common layer and the second common layer are in contact with each other over the partition.
