METHOD FOR MANUFACTURING ORGANIC LIGHT EMITTING ELEMENT

摘要

This invention provides a method for manufacturing an organic light emitting element in which damages to members constituting the organic light emitting element are suppressed and a protective layer with few defects is formed by performing cleaning with liquid containing water. The manufacturing method according to this invention is a method for manufacturing an organic light emitting element including a process of preparing a lower electrode, a process of forming an organic compound layer on the lower electrode, a process of forming an upper electrode on the organic compound layer; and a process of forming a first protective layer on the upper electrode,
in which the method includes, after the process of forming the organic compound layer, a process of cleaning at least one of the organic compound layer, the upper electrode, and the first protective layer with liquid containing water.
