Abstract

A sensor-embedded display panel includes a light emitting element on a substrate and including a light emitting layer, and a photosensor on the substrate and including a photosensitive layer extending at least partially in parallel with the light emitting layer along an in-plane direction of the substrate. The light emitting element and the photosensor include separate, respective portions of each of first and second common auxiliary layers each extending continuously as a single piece of material under and on, respectively, each of the light emitting layer and the photosensitive layer. The photosensitive layer may include a light absorbing semiconductor having a HOMO energy level having a difference of less than about 1.0 eV from a HOMO energy level of the first common auxiliary layer and a LUMO energy level having a difference of less than about 1.0 eV from a LUMO energy level of the second common auxiliary layer.
