Patent ID: 8530254

Claim:
A method of manufacturing an organic electroluminescence device, the organic electroluminescence device comprising a first organic electroluminescence element and a second organic electroluminescence element, the first organic electroluminescence element including a first lower electrode, a first organic electroluminescence layer, and an upper electrode, the second organic electroluminescence element including a second lower electrode, a second organic electroluminescence layer, and the upper electrode, the first organic electroluminescence element emitting color of light different from color of light emitted from the second organic electroluminescence element, the method comprising: forming the first organic electroluminescence layer at least on the first lower electrode; forming a first protective layer on the first organic electroluminescence layer; patterning the first organic electroluminescence layer and the first protective layer so as to selectively remain on the first lower electrode; forming the second organic electroluminescence layer at least on the second lower electrode; forming a second protective layer on the second organic electroluminescence layer; patterning the second organic electroluminescence layer and the second protective layer so as to selectively remain on the second lower electrode; removing the first protective layer and the second protective layer; and forming the upper electrode on the first organic electroluminescence layer and the second organic electroluminescence layer, wherein the second organic electroluminescence layer and the second protective layer, which have been processed by the patterning the second organic electroluminescence layer and the second protective layer, cover an end portion of the first organic electroluminescence layer and an end portion of the first protective layer, which have been processed by the patterning the first organic electroluminescence layer and the first protective layer.
