Display device including alternating pixels and optical sensors

A display device comprising:

• a substrate including an active region and a first non-active region positioned around the active region;
• a plurality of pixels disposed in the active region and emitting light;
• a light source unit disposed in the first non-active region and emitting light;
• a plurality of optical sensors disposed in the active region and sensing incident light emitted by the light source unit;
• and
• an encapsulation layer disposed on the plurality of pixels, the plurality of optical sensors, and the light source unit,
• wherein the plurality of pixels emits light in a wavelength band of visible light, and the light source unit emits light in a wavelength band different from the wavelength band of visible light.

An electronic device comprising:

• a substrate;
• a pixel electrode, a sensing electrode and a first electrode on the substrate;
• a pixel defining layer exposing the pixel electrode, the sensing electrode and the first electrode;
• a first light emitting layer on the pixel electrode;
• a photoelectric conversion layer on the sensing electrode;
• a second light emitting layer on the first electrode;
• and
• a common electrode disposed on the first light emitting layer, the photoelectric conversion layer, the second light emitting layer and the pixel defining layer,
• wherein the second light emitting layer includes a material different from that of the first light emitting layer.
