主权项 1. An organic electroluminescent element comprising: a substrate; a pair of electrodes including an anode and a cathode, disposed on the substrate; and at least one organic layer including a light emitting layer, disposed between the electrodes, wherein at least one kind of compound represented by the following general formula (I) is contained in any layer of the at least one organic layer: wherein R1 to R6 each independently represent a hydrogen atom or a substituent, but there is no case where two adjacent groups out of R1 to R6 are bonded to each other to form a ring; E1 and E2 each independently represents a hydrogen atom or a substituent; of members of only one set of E1 and R2, E1 and R3, E2 and R6, and E2 and R5 are bonded to each other to form a structure represented by the following general formula (E-1), and the members of the other sets are not bonded to each other to form a ring: * represents a position for bonding to the pyrene skeleton; of X1 and X2, one represents a single bond and the other represents any linking group selected from CR111R112, NR113, O, S, and SiR114R115; X3 represents any linking group selected from CR111R112, NR113, O, S, and SiR114R115; R111 to R115 each independently represent a hydrogen atom or a substituent; A1 to A8 each independently represents CR116 or N; R116 represents a hydrogen atom or a substituent, and when two adjacent groups out of A1 to A4 are CR116, the two R116's may be bonded to each other to form a ring structure.
