Photoelectric conversion device and display device comprising the same

A display device comprising:

• a plurality of light emitting portions, wherein the plurality of light emitting portions include a plurality of light emitting elements;
• and
• a sensing portion including a photoelectric conversion device in the sensing portion, wherein the photoelectric conversion device includes a first electrode, a common electrode facing the first electrode, and a hole injection layer, a hole transport layer, a resonance layer having a thickness, and an active layer sequentially stacked between the first electrode and the common electrode, and wherein
• the plurality of light emitting elements include, a pixel electrode, the common electrode facing the pixel electrode, and the hole injection layer, the hole transport layer, the resonance layer, and a light emitting layer sequentially stacked between the pixel electrode and the common electrode, wherein
• a thickness of each of the resonance layers of light emitting elements configured to emit light of different colors are different from each other, and
• a thickness of the resonance layer of at least one of the light emitting elements is the same as a thickness of the resonance layer of the photoelectric conversion device.
