Patent ID: 8076843

Claim:
An organic electroluminescence display device, comprising: a pixel circuit having, over an upper surface of a transparent substrate, a plurality of signal lines and a plurality of scanning lines arranged crossing each other and an organic electroluminescence element in each of pixel areas surrounded by the signal lines and the scanning lines, the pixel areas being defined by an aperture partitioned by banks formed covering the signal lines; and a power supply line for supplying a current to the organic electroluminescence element, and emitting the luminescence from the organic electroluminescence element from a lower surface of the transparent substrate; wherein the power supply line and the signal lines are provided above and directly on an upper surface of a same layer; wherein the power supply line is formed of aluminum; wherein the power supply line is arranged crossing the pixel areas; and wherein the power supply line is arranged on the transparent substrate side of the organic electroluminescence element.
