Abstract:
An aromatic amine derivative is represented by the following formula (1). In the formula (1), R1 to R10 each independently represent a hydrogen atom and a substituent. In the formula (1); R1 is represented by the following formula (2); any one of R2 to R5 and R7 to R10 is represented by the following formula (2); and L1 to L3 each independently represent a single bond, a divalent residue of an aryl group, or the like. In the formula (2); Ar1 is a monovalent substituent having a partial structure represented by the following formula (3); X represents an oxygen atom or a sulfur atom; and A and B represent a six-membered ring. In the formula (2), Ar2 is an aryl group, a monovalent substituent having a partial structure represented by the formula (3), and the like.
