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.

Abstract: An organic EL device including: a substrate; a bank layer having therewithin an opening having an elongated shape in plan view; and a functional layer including an organic material, disposed within the opening, and having an elongated shape in plan view. The bank layer includes first banks opposing each other with the functional layer therebetween in an transverse direction of the functional layer and extending along a longitudinal direction of the functional layer and second banks opposing each other with the functional layer therebetween in the longitudinal direction of the functional layer and extending along the transverse direction of the functional layer. An angle θ2 between an inclined surface of a second bank and an upper surface of the substrate is greater than an angle θ1 between an inclined surface of a first bank and the upper surface of the substrate.
