An organic EL display and a fabrication method high in light extraction efficiency are disclosed, wherein a plurality of organic layers interposed between an emissive layer and a reflective layer can be collectively formed for a plurality of subpixels, thereby reducing the number of mask processes for a lower fabrication cost and higher productivity. The organic EL display comprises a plurality of organic EL cells classified into at least three types of blue light emission, green light emission and red light emission, each including a plurality of organic layers having an emissive layer, a reflective electrode deposited on the first main surface of the organic layers and a transparent electrode deposited on the second main surface of the organic layer. The organic EL cells for green light emission and red light emission have an optical transparent conductive film interposed between the reflective electrode and the organic layer.
