Abstract:
1. An organic electroluminescence display device comprising a plurality of organic electroluminescence elements each having an anode, a cathode and an organic layer sandwiched in between the anode and the cathode, the plurality of organic electroluminescence elements being arranged in a matrix shape to form a display area, wherein: the cathode extends to the exterior of the display area and is supplied with cathode voltage through a plurality of contact holes that are located at an area which is exterior of the display area; and contact pads are formed at the bottoms of the plurality of the contact holes, and a part of the organic layer is sandwiched between the cathode and at least one of the contact pads located in at least one of the contact holes, and wherein, at the at least one contact hole, the part of the organic layer, the cathode and the contact pad are configured and located relative to one another so that a current can flow between the cathode and the contact pad through the part of the organic layer.
