<P>PROBLEM TO BE SOLVED: To provide a color organic light-emitting display device in which light emitting output efficiency and color quality are improved. <P>SOLUTION: In the color organic light-emitting display device having a pixel arrangement divided into two or more different sets of color pixels in which respective color pixel sets emit light in prescribed different colors, this is the color organic light-emitting display device in which respective pixels contained in the constellation include (a) a metal bottom part electrode layer, (b) the organic EL element containing a light emitting layer to emit light of a prescribed color, and (c) the metal upper part electrode layer arranged on the organic EL element arranged on the organic EL element with a certain distance from the metal bottom electrode layer selected so that the light emitting output efficiency of a prescribed color is improved. One of the metal electrode layers is opaque, and the other is substantially not transparent and reflective, the material of the opaque metal electrode and the reflective metal electrode are selected from specific materials, and the thickness of the opaque metal electrode layer and the position of the light emitting layer between the electrodes are selected so that the light emitting output efficiency becomes higher. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
