摘要：
A charge transporting material which allows for a low driving voltage and is superior in luminous efficiency and durability is provided. The charge transporting material comprising a compound represented by any one of the general formula (1-1) to (1-3) wherein R111 to R114, R121 to R125 and R131 to R135, L111 to L113, and L121 to L123 are as defined in the specification. Ar111 to Ar113 represent a substituent represented by any one of the general formulae (3-1) to (3-3); * represents a binding position to L121 to L123; and R311, R312, R321 to R325 and R331 to R335 are as defined in the specification:
