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.
