Abstract
A sensor-embedded display panel includes a light emitting element and a sensor which include separate portions of a first common auxiliary layer including a hole transport material and a second common auxiliary layer including an electron transport material. The sensor includes first and second semiconductor layers proximate to the first and second common auxiliary layers, respectively, and including a p-type semiconductor and a non-fullerene n-type semiconductor having a LUMO energy level deeper than that of the electron transport material, respectively. An insertion layer between the second semiconductor layer and the second common auxiliary layer includes a metal, a metal compound, or any combination thereof. A work function of the metal or a LUMO energy level of the metal compound is deeper or shallower than the LUMO energy level of the non-fullerene n-type semiconductor and the LUMO energy level of the electron transport material within less than about 1.3 eV, respectively.
