Patent ID: 7485893

Claim:
An organic electroluminescent device, comprising: a substrate; a sub-electrode layer disposed over the substrate; a signal line electrode layer disposed to cover the sub-electrode layer and configured to electrically communicate with the sub-electrode layer; an insulating layer disposed over the sub-electrode layer; an anode electrode layer disposed over the substrate; a cathode electrode layer disposed over or under the anode electrode layer; and an organic material layer disposed between the anode electrode layer and the cathode electrode layer, wherein a pixel area is defined as an area of the substrate covered by the anode electrode layer, the organic material layer and cathode electrode layer, wherein a signal line is defined as a structure including the sub-electrode layer and the signal line electrode layer, and is in electrical communication with the cathode electrode layer or the anode electrode layer, wherein the signal line consists of only the sub-electrode layer in a predetermined area of the signal line, wherein the sub-electrode layer of the predetermined area contacts the cathode electrode layer, and wherein the insulating layer disposed over the sub-electrode layer of the predetermined area to cover an end of the signal line electrode layer.
