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