Abstract
An organic electroluminescence display device wherein the wiring width is made large enough to secure a current capacity for the power supply line and at the same time high luminance is achieved by increasing the aperture rate is to be realized. The device has lower electrodes formed over the main face of a transparent substrate, a plurality of organic electroluminescence elements each stacked over one or another of the lower electrodes and emitting light of a prescribed color, and an upper electrode formed as a film covering the plurality of organic electroluminescence layers in common, and this upper electrode is reflective and the luminescence from the organic electroluminescence elements is emitted from the transparent substrate side. The device further has: a pixel circuit including, over the inner face of the transparent substrate, a plurality of signal lines and a plurality of scanning lines arranged crossing each other and an organic electroluminescence layer in each of pixel areas surrounded by the signal lines and the scanning lines; and a power supply line for supplying a current to the organic electroluminescence layer, wherein the pixel line is arranged across the pixe…
