Abstract
Official abstract text for this publication.
An ink for an organic light-emitting element includes a first solvent, a second solvent, and a functional material. The first and second solvents have equal or similar boiling points. 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 the top surfaces of the end portions are positioned higher than the 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 the top surface of the central portion is positioned higher than the top surfaces of the end portions.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ink for an organic light-emitting element, the ink comprising: a first solvent; a second solvent that differs from the first solvent; a third solvent that differs from the first and second solvents; and a functional material that is soluble in the first solvent and the second solvent and that forms a functional layer of the organic light-emitting element, wherein the first solvent is a solvent such that when the second and third solvents are…
