Abstract:
An aromatic amine derivative is represented by a formula (1) below. In the formula (1), R2 to R5, R7 to R9 and R10 are each independently a hydrogen atom or a substituent. In the formula (1), R1 and R6 are represented by a formula (2) below, and L1 to L3 are each independently a single bond and the like. In the formula (2), Ar1 is a monovalent residue derived from the ring structure represented by a formula (4) below, X is an oxygen atom or a sulfur atom, and at least one of R11 to R18 is an alkyl group. In the formula (1), Ar2 is an aryl group or a monovalent residue derived from the ring structure represented by the formula (4).
