An organic electroluminescence device comprising: a substrate; a pair of electrodes disposed on the substrate and including an anode and a cathode; and at least one organic layer disposed between the electrodes and including a light-emitting layer; and any one of the at least one organic layer It contains at least one compound represented by the following formula, and has good luminous efficiency, driving voltage, and driving durability, and has low vapor deposition rate dependence (in the formula, X represents O atom, S atom, CR12R13, NR14 or SiR15R16. R12, R13, R14, R15 and R16 represent each independently a fluorine atom, an alkyl group, an aryl group or a heteroaryl group. R1 to R8 each represent a hydrogen atom or a substituent independently of each other. Adjacent R1 to R8 are bonded to each other to form a ring, or R7 or R8 may be bonded to a substituent which may be possessed by an adjacent X or Q. The Q system represents a substituted or unsubstituted aromatic group having 6 to 30 carbon atoms. A hydrocarbon ring or a substituted or unsubstituted aromatic ring having 4 to 30 ring members. □ |
