ABSTRACT:
An organic electro luminescence display comprises a pixel portion on which a plurality of pixels are arranged with a first electrode, a second electrode, and an organic thin film layer interposed between the first and second electrodes, a first power line supplying a first level voltage to the pixels of the pixel portion; and a second power line having at least a region overlapped with the second electrode to supply a second level voltage to the second electrode, and an insulating layer having a plurality of contact holes in the overlapped region between the second power line and the second electrode. The sum of the circumferences of each contact hole is greater than the circumference of the overlapped region.
