Abstract
An ink for forming a functional layer includes a first component that contains at least one kind of aromatic solvent of which a boiling point is higher than or equal to 250° C. and lower than or equal to 350° C., a second component that contains at least one kind of aliphatic solvent of which a boiling point is higher than or equal to 200° C., and a third component for forming a positive hole injection layer, in which a solubility of the third component in the first component is higher than the solubility of the third component in the second component, a mixing ratio of the second component is 30 vol %, the boiling point of the first component is higher than the boiling point of the second component, and a difference between the boiling points thereof is higher than or equal to 30° C.
