Abstract
A method of manufacturing an organic electroluminescence display device includes an organic compound layer which is placed between a pair of electrodes and includes at least an emission layer, the organic compound layer being two-dimensionally arranged, includes forming the organic compound layer which is insoluble in water in an entire emission region on a substrate, providing a mask layer containing a water-soluble material in at least a part of a region on the organic compound layer, removing a part of the organic compound layer which is provided in a region which is other than the region in which the mask layer is provided, removing the mask layer, and forming, after the removing of the mask layer, a layer containing at least an alkali metal or an alkaline-earth metal in a region including at least the emission region.
