Organic electroluminescent display device and method of manufacturing the same

摘要

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.

1. A method of manufacturing an organic electroluminescent display device, comprising the steps of:
preparing a substrate on which a plurality of pixel electrodes are disposed; forming an insulating layer in the areas between the respective adjacent pixel electrodes so as to rest on ends of the respective pixel electrodes, forming an organic electroluminescent film to rest on the insulating layer, with the inclusion of a common layer that continuously covers the plurality of pixel electrodes; forming a common electrode on the organic electroluminescent film; and irradiating the common layer with an energy ray above the areas between the respective adjacent pixel electrodes with the avoidance of irradiation above the organic electroluminescent film, wherein an electric conductivity of the common layer is reduced above the areas between the respective adjacent pixel electrodes, by irradiation of the energy ray.
