Abstract:
1. An organic electroluminescent display device, comprising: a substrate divided into an pixel area and a scan line area disposed at outer side of the pixel area; a plurality of pixels disposed over the substrate in the pixel area; and a plurality of scan lines disposed over the substrate in the scan line area, wherein each pixel comprises an anode electrode layer, a cathode electrode layer and an organic layer disposed between the anode and cathode electrode layers, and the scan line comprises a scan line electrode layer disposed over the substrate, a first sub-electrode layer disposed over the scan line electrode layer and configured to electrically communicate with the scan line, a conducting layer disposed over the first sub-electrode layer and configured to electrically communicate with the first sub-electrode layer, and a second sub-electrode layer disposed over the conducting layer, wherein the cathode electrode layer extends from the pixel area towards the scan line area to be in electrical communication with the conducting layer, and wherein an electrical conductivity of the conducting layer is substantially identical with an electrical conductivity of the cathode electrode layer, wherein the cathode electrode layer is disposed to electrically connect with a side portion of the conducting layer, and wherein the scan line electrode layer, the first sub-electrode layer, the conducting layer, and the second sub-electrode layer are all disposed to expose at least one portion of the substrate over the scan line area, and wherein the cathode electrode layer is disposed to fill in the at least one portion of the substrate over the scan line area.
