A sub-pixel is provided in a display area of an organic EL display device. A bank layer surrounds an outer periphery of the sub-pixel. A contact area is positioned in the display area and is adjacent to the sub-pixel through the bank layer. A pixel electrode is provided in the sub-pixel. A common electrode is disposed across the sub-pixel and the contact area. At least a part of an auxiliary conductive layer is positioned in the contact area. A contact hole is provided in the contact area and electrically connects the common electrode and the auxiliary conductive layer.
