Abstract:
An organic electroluminescent element containing a light emitting material represented by the following general formula (1) and a host material represented by the general formula (H-1) in a light emitting layer. The organic electroluminescent element has low driving voltage, high luminous efficiency, and excellent durability. L represents O, NRC0, or CRC1RC2; RC0 to RC2 each represents a hydrogen atom or a substituent; RC3 to RC6 each represents a substituent; nC3 and nC6 each represents an integer of 0 to 3; nC4 and nC5 each represents an integer of 0 to 4; RH111 to RH118 each represents a hydrogen atom or a substituent; X represents any one of O, S, NRH119, CRH120RH121, and SiRH122RH123, and RH119 to RH123 each represents a substituent; the ring A represents a benzene ring; and the ring B represents a 5- or 6-membered ring.
