Patent ID: 8877532

Claim:
A method of manufacturing an organic electroluminescence display device including multiple electroluminescence elements, each of the multiple electroluminescence elements including a first electrode and a second electrode and an organic compound layer provided between the first electrode and the second electrode, the organic compound layer including at least an emission layer, the method comprising: forming on a substrate having the first electrode provided thereon the organic compound layer which is insoluble in water; forming, on the organic compound layer, a first mask layer comprising a water-soluble material and a second mask layer comprising silicon nitride or silicon oxide in this order; forming a resist layer on the second mask layer to conduct patterning using photolithography; removing a part of the organic compound layer, the second mask layer, and the first mask layer, which are formed in a region in which the resist layer is not provided; removing the first mask layer by contact with a solvent containing water; forming, after the removing of the first mask layer, a continuous layer containing one of an alkali metal and an alkaline-earth metal over the multiple electroluminescence elements; and forming the second electrode on the layer containing one of the alkali metal and the alkaline-earth metal.
