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 the light emitting layer contains a luminescent compound represented by the following general formula (1):

OG Complex Work Unit Chemistry
wherein R1 to R14 each independently represents a hydrogen atom, a deuterium atom, an alkyl group, an aryl group, a heteroaryl group, a fluorine atom, a cyano group, an amino group, an alkoxy group, an aryloxy group, a thio group, or a silyl group, and these may be bonded to each other to form a ring;
wherein at least one of R1 to R14 is an amino group, wherein the amino group is represented by NR15R16,
wherein R15 and R16 each independently represent an alkyl group, an aryl group, a heteroaryl group, or a hydrogen atom; and
wherein one of R15 and R16 is bonded to an adjacent R1 to R14 to form a ring which may be further substituted.
