    Abstract: A sensor embedded display panel includes a substrate, a light emitting element on the substrate and including an emission layer; and a photoelectric element on the substrate. The photoelectric element includes a light absorbing layer. The light absorbing layer at least partially overlaps the emission layer in a horizontal direction extending in parallel to an upper surface of the substrate. The light emitting element and the photoelectric element each include a separate portion of a first common auxiliary layer that extends on tops of the emission layer and the light absorbing layer and a separate portion of a second common auxiliary layer that extends on bottoms of the emission layer and the light absorbing layer. The photoelectric element further includes an auxiliary layer that has a thickness corresponding to one of a red wavelength spectrum, a green wavelength spectrum, or a blue wavelength spectrum.
