Abstract:
1. A method of manufacturing an organic EL display, comprising: providing an organic EL panel including a substrate and organic EL devices disposed over the substrate in a matrix arrangement, the organic EL devices each including a pixel electrode disposed over the substrate, an organic layer disposed over the pixel electrode, a transparent counter electrode disposed over the organic layer, a protective layer disposed over the transparent counter electrode, and a color filter disposed over the protective layer; detecting a defect present in the organic layer of each of the organic EL devices; destroying a portion of the transparent counter electrode directly above the defect by applying a laser beam to the portion through the color filter; and removing a portion of the color filter directly above the defect such that beams of light diffused over the defect travel to outside through a portion from which the color filter has been removed, wherein
