Abstract
A sensor-embedded display panel includes a substrate, a light emitting element on the substrate and including a light emitting layer, and a photosensor on the substrate and including a photoelectric conversion layer in parallel with the light emitting layer along an in-plane direction of the substrate, wherein the light emitting element and the photosensor each include a separate portion of a first common auxiliary layer that is a single piece of material that extends continuously on the light emitting layer and the photoelectric conversion layer, and a separate portion of a common electrode on the first common auxiliary layer and is configured to apply a common voltage to both the light emitting element and the photosensor, and the photoelectric conversion layer includes a sequential stack from the first common auxiliary layer of a first n-type semiconductor layer, a second n-type semiconductor layer, and a p-type semiconductor layer.
