First claim
Opening claim text (preview).
What is claimed is: 1 . An organic photodetector comprising: a substrate; a first electrode arranged on the substrate; a second electrode arranged on the substrate and apart from the first electrode in a first direction crossing a direction perpendicular to the substrate; and an active layer covering the first electrode and the second electrode. 2 . The organic photodetector of claim 1 , wherein the first electrode and the second electrode are arranged on the same layer. 3 . The organic photodetector of claim 1 , wherein the active layer comprises: a p-type semiconductor layer comprising a p-type organic semiconductor; and an n-type semiconductor layer comprising an n-type organic semiconductor. 4 . The organic photodetector of claim 3 , wherein the active layer is a mixed layer of the p-type organic semiconductor and the n-type organic semiconductor. 5 . The organic photodetector of claim 3 , wherein the p-type organic semiconductor comprises SubPc, CuPc, DBP, or any combination thereof, and the n-type organic semiconductor comprises C60 fullerene, C70 fullerene, or any combination thereof. 6 . The organic photodetector of claim 1 , further comprising: a third electrode arranged on the substrate; and an insulating layer covering the third electrode. 7 . The organic photodetector of claim 6 , wherein the insulating layer covers an upper surface and a side surface of the third electrode. 8 . The organic photodetector of claim 6 , wherein the active layer covers the insulating layer. 9 . The organic photodetector of claim 6 , wherein the third electrode is arranged on the same layer as the first electrode and the second electrode. 10 . An electronic device comprising: a substrate; an organic photodetector comprising a first electrode arranged on the substrate, a second electrode arranged on the substrate and apart from the first electrode in a first direction crossing a direction perpendicular to the substrate, and an active layer covering the first electrode and the second electrode; and a light-emitting element comprising a pixel electrode arranged on the substrate, a counter electrode arranged on the pixel electrode, and a light-emitting layer arranged between the pixel electrode and the counter electrode. 11 . The electronic device of claim 10 , wherein the first electrode and the second electrode are arranged on the same layer. 12 . The electronic device of claim 10 , wherein the active layer comprises: a p-type semiconductor layer comprising a p-type organic semiconductor; and an n-type semiconductor layer comprising an n-type organic semiconductor. 13 . The electronic device of claim 12 , wherein the active layer is a mixed layer of the p-type organic semiconductor and the n-type organic semiconductor. 14 . The electronic device of claim 10 , further comprising: a third electrode arranged on the substrate; and an insulating layer covering the third electrode. 15 . The electronic device of claim 14 , wherein the third electrode is arranged on the same layer as the first electrode and the second electrode. 16 . The electronic device of claim 10 , wherein the pixel electrode is arranged on the same layer as the first electrode. 17 . The electronic device of claim 10 , wherein the light-emitting element comprises: a first common layer arranged between the pixel electrode and the light-emitting layer; and a second common layer arranged between the light-emitting layer and the counter electrode. 18 . The electronic device of claim 17 , wherein the substrate comprises a light-emitting area and a sensing area, the light-emitting element is arranged to correspond to the light-emitting area, and the organic photodetector is arranged to correspond to the sensing area. 19 . The electronic device of claim 18 , wherein the pixel electrode and the light-emitting layer are arranged to correspond to the light-emitting area. 20 . The electronic device of claim 18 , wherein the first common layer and the second common layer are arranged entirely in the light-emitting area and the sensing area.
