An organic electroluminescence device using a compound represented by the following formula has a dark blue luminescence, and has a high voltage suppression effect at the time of high luminance driving. [R1 to R6 represent a hydrogen atom or a substituent; E1 and E2 each independently represent a hydrogen atom or a substituent; and E1 and R2, E1 and R3, E2 and R6, and at least one of E2 and R5 are bonded to each other to form the following The structure shown by the linker; one of X1 and X2 represents a single bond, the other represents any of CR111R112, NR113, O, S and SiR114R115; X3 represents any of CR111R112, NR113, O, S and SiR114R115 a linking group; R111 to R115 represent a hydrogen atom or a substituent; A1 to A8 represent CR116 or N; and R116 represents a hydrogen atom or a substituent. ]□ |
