The invention provides an organic EL display device in which at least two electrodes and organic EL layers are alternately provided on a substrate respectively, and the electrodes thus provided have an anode and a cathode formed alternately. In the organic EL display device according to the invention, at least two organic EL layers are provided. As compared with a conventional organic EL display device having one organic EL layer, therefore, an emission luminance is increased to be a double or more.
