Patent ID: 7915073

Claim:
A method of manufacturing an organic EL display panel in which a vapor deposition mask having a plurality of opening portions in a predetermined pattern is adhered to a surface of a substrate which constitutes an organic EL display panel, and a thin film pattern corresponding to the predetermined pattern is formed on a surface of the substrate through the opening portions of the vapor deposition mask by means of a thin film layer forming means, wherein the plurality of opening portions of the vapor deposition mask are formed in the inside of a recessed surface which is retracted from a surface on which the vapor deposition mask is brought into contact with the substrate, a gap space is formed between the plurality of opening portions of the vapor deposition mask and the surface of the substrate, and the thin film pattern is vapor-deposited by making the plurality of opening portions of the vapor deposition mask spaced apart from the substrate with a predetermined gap, wherein the recessed surface faces the surface of the substrate.
