Patent ID: 8664017

Claim:
A method of manufacturing an organic light emitting device, the organic light emitting device comprising: a substrate on which a first region and a second region are provided, the first region being a light emitting region having multiple light emitting portions, the second region being provided on a periphery of the first region; and first electrodes formed respectively in areas corresponding to the multiple light emitting portions, the method comprising: a first organic compound layer formation step of forming a first organic compound layer including a first emission layer at least in the first region; a first protective layer formation step of forming a first protective layer including a release layer over an entire surface of the substrate on which the first organic compound layer is formed; a second protective layer formation step of forming a second protective layer on the first protective layer; a second protective layer processing step of removing a part of the second protective layer to obtain a patterned second protective layer; a first protective layer and first organic compound layer processing step of removing a part of the first protective layer and the first organic compound layer in accordance with the pattern of the second protective layer to obtain a patterned first protective layer and a patterned first organic compound layer; a second organic compound layer formation step of forming a second organic compound layer including a second emission layer over an entire surface of the substrate on which the patterned first organic compound layer is formed; and a lift-off step of bringing the release layer into contact with release agent for selectively removing the release layer, to thereby remove at least the release layer together with a layer formed above the release layer, wherein an area from which the second protective layer is removed in the second protective layer processing step is provided also in the second region, and wherein a minimum value of an interval between areas from which the second protective layer is removed in the second region is 100 times or less a minimum value of an interval between areas from which the second protective layer is removed in the first region.
