    摘要: A display panel may include a light emitting element including a light emitting layer and a sensor including a photosensitive layer on a substrate. The light emitting element and the sensor each may include respective portions of first and second common auxiliary layers, which may be continuous under and over the light emitting layer and the photosensitive layer. The first and second common auxiliary layers respectively may include a hole transport material and an electron transport material. The photosensitive layer may include first and second semiconductor layers close to the first and second common auxiliary layers, respectively. The first and second semiconductor layers respectively may include a p-type semiconductor and an n-type semiconductor. The second semiconductor layer may have an uneven surface facing the second common auxiliary layer and may have an average roughness (Rq) of greater than or equal to about 5 nm.

    摘要: 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.
