Abstract: In an organic EL display device, a resistance of a cathode electrode of OLEDs is substantially reduced while maintaining a higher opening ratio of pixels as an entire display area. A reference power supply line is formed on a glass substrate, and receives a reference potential for driving the OLED. The OLED is formed on the glass substrate where the reference power supply line is formed, and has a structure in which a lower electrode, an organic material layer, and an upper electrode that is a cathode electrode common to plural pixels are laminated on each other in the order from the bottom. In some of the plural pixels, a cathode contact that penetrates through the organic material layer, and electrically connects the upper electrode to the reference power supply line is formed within an opening area corresponding to a W sub-pixel.

Abstract: A substrate on which a plurality of pixel electrodes are disposed is prepared. An organic electroluminescent film 22 is formed with the inclusion of a common layer that continuously covers the plural pixel electrodes. A common electrode is formed on the organic electroluminescent film. The common layer is irradiated with an energy ray above areas between the respective adjacent pixel electrodes with the avoidance of irradiation above the plural pixel electrodes. An electric conductivity of the common layer is reduced above the areas between the respective adjacent pixel electrodes, by irradiation of the energy ray. With this configuration, a current leakage can be prevented between the adjacent pixels.
