Claim:
1. An ink composition comprising: the following component (A); the following component (B); and the following component (C), the component (A) being an anthracene derivative represented by the following formula (A1): in the formula (A1), L is one of a single bond, a substituted or unsubstituted arylene group including 6 to 50 ring-forming carbon atoms, and a heteroarylene group including 5 to 50 ring-forming atoms, each of A1 and A2 is one of a substituted or unsubstituted aryl group including 6 to 50 ring-forming carbon atoms, and a heteroaryl group including 5 to 50 ring-forming atoms, l is an integer of 0 to 9, m is an integer of 0 to 8, and X is one of an oxygen atom and a nitrogen atom, where when each of l and m is 2 or more, a plurality of A1's are the same as or different from one another, a plurality of A2's are the same as or different from one another, adjacent A1's are optionally bonded to form a ring, and adjacent A2's are optionally bonded to form a ring, the component (B) being an aromatic amine derivative represented by the following formula (B1): in the formula (B1), each of R1 to R8 is one of a hydrogen atom and a substituent group, and each of Ar1 to Ar4 is one of a substituted or unsubstituted aryl group including 6 to 30 ring-forming carbon atoms, and a substituted or unsubstituted heterocyclic group including 5 to 30 ring-forming atoms, where one or more of Ar1 to Ar4 are a heterocyclic group represented by the following formula (B1′), in the formula (B1′), each of R11 to R17 is one of a hydrogen atom and a substituent group, adjacent substituent groups in R11 to R17 optionally form a saturated or unsaturated ring, and X1 is one of an oxygen atom and a sulfur atom, and the component (C) being a solvent represented by the following formula (C1) and having a boiling point of 110° C. or higher and a solubility of 1 wt % or less in water: in the formula (C1), R is a substituent group, and n is an integer of 1 to 6 both inclusive, where when n is 2 or more, a plurality of R's are the same as or different from one another.
