摘要： 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.

摘要： A method of efficiently manufacturing an organic light-emitting element with excellent light-emitting characteristics is provided. The method includes: preparing ink and filling an inkjet device having an ink ejection nozzle with the ink; preparing a substrate having a base layer including a first electrode; positioning the inkjet device above the substrate; and causing the inkjet device to eject a drop of the ink onto the base layer. In the preparation of the ink, a value Z denoting a reciprocal of the Ohnesorge number Oh determined by density ρ (g/dm3), surface tension γ (mN/m), and viscosity η (mPa·s) of the ink and a diameter r (mm) of the ink ejection nozzle satisfies Formula 1, in the ejection of the drop of the ink, speed V (m/s) of the ejected drop satisfies Formula 2, and the value Z and the speed V (m/s) satisfy Formula 3.
