Display device

A display device comprising:

• a first insulating layer;
• a wiring under the first insulating layer;
• a pixel electrode on the first insulating layer;
• a second insulating layer on an end of the pixel electrode;
• a light-emitting layer covering an upper surface of the pixel electrode except for an end part that is covered by the second insulating layer;
• a counter electrode covering the light-emitting layer and the second insulating layer;
• and
• a photoelectric conversion element inside the second insulating layer, the photoelectric conversion element including a p-type semiconductor layer and an n-type semiconductor layer arranged side by side in a direction along the upper surface of the pixel electrode, a first one of the p-type semiconductor layer and the n-type semiconductor layer being connected to the counter electrode, a second one of the p-type semiconductor layer and the n-type semiconductor layer having a lower surface that includes a first lower surface area that is connected to the wiring and a second lower surface area that is in contact with the second insulating layer, wherein,
• the p-type semiconductor layer and the n-type semiconductor layer have mutually opposed surfaces in planes perpendicular to the upper surface of the pixel electrode.
