Abstract

A method of manufacturing a light-emitting element. The method includes forming an underlayer that includes a reflective electrode, forming a bank that has liquid repellency, irradiating the bank with characteristic energy rays to decrease liquid repellency of the bank, and forming a functional layer. The bank is formed on the underlayer and is provided with an opening and an inclined portion surrounding the opening. The opening has a shape that has a long axis and a short axis and is positioned above the reflective electrode. In plan view, end sections of the inclined portion in a direction of the long axis overlap the upper surface of the reflective electrode, while central sections of the inclined portion in the direction of the long axis do not overlap the upper surface of the reflective electrode.
