Abstract:
1. A method for manufacturing an organic electroluminescence display having an organic film and first and second electrode layers, the first and second electrode layers facing each other to interpose the organic film therebetween and allow the organic film to emit light passing through the first electrode layer, said method comprising the steps of: inspecting whether the organic film emits light or not; if the organic film does not emit light, detecting foreign matter in the organic film from a side of the first electrode layer; and if the foreign matter is detected, irradiating the second electrode layer with a laser beam capable of transmitting the first electrode layer and the organic film by way of an optical path free of the foreign matter, so as to remove a closed band-like region of the second electrode layer surrounding a periphery of the foreign matter from the second electrode layer, wherein an island region of the second electrode layer is isolated from a remaining region of the second electrode layer by an area of the organic film being exposed by removing the closed band-like region of the second electrode layer, and the foreign matter exists under the island region in the organic film.
