1. A sensor embedded display panel, comprising:
a substrate;
a light emitting element on the substrate, the light emitting element including an emission layer; and
a photoelectric element on the substrate, the photoelectric element including a light absorbing layer, the light absorbing layer at least partially overlapping the emission layer in a horizontal direction extending in parallel to an upper surface of the substrate,
wherein each of the light emitting element and the photoelectric element include
a separate portion of a first common auxiliary layer that extends on both a top of the emission layer and a top of the light absorbing layer, and
a separate portion of a second common auxiliary layer that extends on both a bottom of the emission layer and a bottom of the light absorbing layer,
wherein the photoelectric element includes a first sensor pixel configured to convert incident light of a red wavelength spectrum into a first electrical signal, a second sensor pixel configured to convert incident light of a green wavelength spectrum into a second electrical signal, and a third sensor pixel configured to convert incident light of a blue wavelength spectrum into a third electrical signal, and
wherein the first sensor pixel includes a first auxiliary layer that has a first thickness, the second sensor pixel includes a second auxiliary layer that has a second thickness, and the third sensor pixel includes a third auxiliary layer that has a third thickness, the second thickness smaller than the first thickness, the third thickness smaller than the second thickness.
