Abstract

A functional layer of an organic light-emitting element is formed by using an ink including a first solvent and a second solvent having equal or similar boiling points, and a functional material. The first solvent is such that an imitatively formed functional layer formed by replacing the second solvent with the first solvent, in a light-emitting region of an organic light-emitting element, is thicker at both end portions than at a central portion and top surfaces of the end portions are positioned higher than a top surface of the central portion. The second solvent is such that an imitatively formed functional layer formed by replacing the first solvent with the second solvent, in a light-emitting region of an organic light-emitting element, is thicker at a central portion than at both end portions and a top surface of the central portion is positioned higher than top surfaces of the end portions.
