20120001124 | INK FOR ORGANIC ELECTROLUMINESCENT DEVICE, MANUFACTURING METHOD OF ORGANIC ELECTROLUMINESCENT DEVICE, ORGANIC DISPLAY PANEL, ORGANIC DISPLAY APPARATUS, ORGANIC ELECTROLUMINESCENT APPARATUS, INK , FORMING METHOD OF FUNCTIONAL LAYER, AND ORGANIC ELECTROLUMINESCENT DEVICE - An ink for an organic electroluminescent device includes a functional material, a first solvent, a second solvent, and a third solvent. The functional material is for forming a functional layer of the organic electroluminescent device. The first solvent is for dissolving the functional material. The second solvent has a diester backbone and a second boiling point that is at most equal to a first boiling point of the first solvent or greater than the first boiling point of the first solvent by at most 20° C. The third solvent is an aliphatic alcohol and has a third boiling point that is less than the first boiling point of the first solvent and less than the second boiling point of the second solvent. | 01-05-2012 |
20130082249 | METHOD FOR MANUFACTURING ORGANIC LIGHT-EMITTING ELEMENT, ORGANIC LIGHT-EMITTING ELEMENT, ORGANIC DISPLAY DEVICE, ORGANIC LIGHT-EMITTING DEVICE, METHOD FOR FORMING FUNCTIONAL LAYER, FUNCTIONAL MEMBER, DISPLAY DEVICE, AND LIGHT-EMITTING DEVICE - 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. | 04-04-2013 |
