Abstract:
1. A method for manufacturing a light-emitter, comprising: a first step of forming, on a substrate, an underlayer including a first electrode; a second step of forming an interlayer on the underlayer; a third step of forming, on the interlayer, a resin material layer including a photosensitive resin material; a fourth step of, by partially exposing the resin material layer and then developing the resin material layer using developer in which the resin material layer and the interlayer are soluble, removing an uncured portion of the resin material layer to form an opening penetrating to the interlayer, and infiltrating the developer into the interlayer via the opening to remove at least surfaces of first and second portions of the interlayer, the first portion corresponding in position to the opening, the second portion surrounding the first portion; a fifth step of forming each of a plurality of banks from the resin material layer by heating a portion of the resin material layer remaining after the fourth step to soften an overhanging portion of the resin material layer above a space formed by the surface of the second portion being removed, so that the overhanging portion flows downward to fill the space, cover a portion of the interlayer exposed to the space, and be in contact with the underlayer or the interlayer; a sixth step of forming, in an area defined by adjacent banks of the plurality of banks, a functional layer including an organic light-emitting layer; and a seventh step of forming a second electrode on the functional layer.
