METHOD FOR MANUFACTURING ORGANIC LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for organic light-emitting device capable of suppressing defective patterning to be generated by the residual of a peeling layer.SOLUTION: A method for manufacturing an organic light-emitting device at least has: a formation step of a first organic compound layer; a formation step of a first protective layer; a formation step of a second protective layer; a processing step of the second protective layer; a processing step of the first protective layer; a processing step of the first organic compound layer; a formation step of a second organic compound layer; and a lift-off step. A pattern of the second protective layer to be obtained by the processing step of the second protective layer is formed also in a second area.
