Method of manufacturing substrate, method of manufacturing organic electroluminescent display device using the method, and organic electroluminescent display device

摘要

A method of manufacturing an organic electroluminescent display device includes preparing an auxiliary substrate, which has a flat side; forming a first protective layer on the auxiliary substrate; forming an organic electroluminescent unit on the first protective layer; bonding a flexible main substrate onto the organic electroluminescent unit; and etching the auxiliary substrate to remove the same.
