Abstract
An organic EL display that realizes low electric power consumption and display with high brightness by decreasing the resistance of the electrode on the scanning side is provided. The display device of the invention includes a substrate, first electrodes in a stripe form comprising a transparent conductive material formed on the substrate, an insulating film having prescribed openings formed on the first electrodes, an organic layer comprising an organic light emitting material formed on the openings and the insulating film, and second electrodes in of a stripe form formed on the organic layer, wherein the first electrodes comprise a material having a large resistance than a resistance of the second electrodes, the first electrodes and the seconds electrode are arranged to cross each other, the organic layer is formed only in the crossing part of the first electrodes and the second electrodes, a first circuit supplying a first electric current is connected to the first electrodes, and a second circuit supplying a second electric current larger than the first electric current is connected to the second electrodes.
