Claim:
1. An ink for functional layer formation, comprising: a first component that is a solute; a second component having a first boiling point of 280° C. or greater and 350° C. or less, being a good solvent for the first component, and being at least one type selected from a group consisting of an aromatic hydrocarbon including at least two aromatic rings, aromatic glycol ether, aliphatic glycol ether, aliphatic acetate, and aliphatic ester; a third component having a second boiling point of 200° C. or greater and 300° C. or less, being a good solvent for the first component, and being at least one type selected from a group consisting of an aromatic hydrocarbon, an aromatic ether, and an aliphatic ether, wherein the proportion of the second component in a mixed solvent including the second component and the third component is 10 wt % or greater, the first boiling point is greater than the second boiling point, a difference between the first boiling point and the second boiling point is 50° C. or greater, a viscosity of the second component is greater than a viscosity of the third component, and the second component is 1,1-bis(3,4-dimenthyl phenyl ethane).
