Claim Text:
1. A method of manufacturing a light-emitting element, comprising: forming an underlayer on a substrate, the underlayer including a reflective electrode; forming, on the underlayer, a bank having liquid repellency and provided with an opening and an inclined portion surrounding the opening, the opening having a shape that has a long axis and a short axis and being positioned above the reflective electrode; radiating energy rays from above the bank towards the bank, the energy rays being transmitted through the bank, being reflected upwards at an upper surface of the reflective electrode, and causing the liquid repellency of the bank to decrease; and forming, on the underlayer, a functional layer within the opening, wherein in forming the bank, 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.
