| description | To provide an organic electroluminescent device realizing high efficiency and low voltage characteristics. A light-emitting layer including compounds of (1) and (2) and a dopant is included. X represents N or CR3, wherein at least one X represents N. R1 represents (1b), R2 represents (1c), and R3 represents an alkyl group or the like. Y represents O, S, NR4, or CR5R6, R4 to R6 each represent an alkyl group or the like, and one of R7 to R14 binds to a ring in (1). * represents a binding position to a ring in (1), and rings C and D are each an aromatic ring fused to an adjacent ring. R15, R16 and R17 have the same meaning as R3 (a and b represent the number of substitutions) . R19 has the same meaning as R4, and R20 to R27 each represent CR3, CR28 or N and at least one thereof represents CR28, and R28 represents formula (2b). Z represents O, S, NR37, or CR38R39, R37 to R39 each has the same meaning as R4, and one of R29 to R36 binds to a ring in (2) and the others represent CR3 or N. |
