Abstract
Provided is a method of manufacturing a display apparatus, including forming a drive circuit and a light-emitting portion on a substrate in which the forming the light-emitting portion includes forming a transparent anode electrode for applying a charge to an emission layer, forming a first coating layer and a second coating layer on the transparent anode electrode, removing the first coating layer by etching using the second coating layer as a mask, and forming a layer including the emission layer on a part of the transparent anode electrode from which the first coating layer is removed. A surface of the transparent anode electrode becomes as clean as a surface cleaned with ultraviolet irradiation.
