Claim 7:
8. A display device, comprising:
a display panel that includes a lower surface and an upper surface opposite to the lower surface, and a plurality of pixels disposed on the upper surface of the display panel; and
an optical sensor disposed on the lower surface of the display panel and that includes a plurality of sensor pixels,
wherein each sensor pixel comprises:
a substrate;
a photoelectric element disposed on the substrate, wherein the photoelectric element includes a first electrode, an intermediate layer disposed on the first electrode, and a second electrode disposed on the intermediate layer;
a barrier layer disposed on the second electrode;
an insulating layer that covers the photoelectric element and the barrier layer;
a bias electrode disposed on the insulating layer and electrically connected to the second electrode; and
an organic planarization layer disposed directly on the bias electrode and the insulating layer,
wherein the insulating layer is in contact with the intermediate layer, but is spaced apart from the second electrode.
