摘要:
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 includes a compound represented by the following general formula: (R1, R2, and R19 each independently represent a hydrogen atom, a phenyl group, a monovalent oligoaryl group having the number of rings of from 2 to 10, or a monovalent fused polycyclic aromatic hydrocarbon group having the number of rings of from 2 to 6, provided that at least one of R1, R2, and R19 represents a monovalent oligoaryl group having the number of rings of from 2 to 10 or a monovalent fused polycyclic aromatic hydrocarbon group having the number of rings of from 2 to 6, and that the phenyl group, the monovalent oligoaryl group having the number of rings of from 2 to 10, and the monovalent fused polycyclic aromatic hydrocarbon group having the number of rings of from 2 to 6 do not have an amino group as a substituent; R11 to R18 each independently represent a hydrogen atom or a substituent; and A1 to A4 each independently represent a nitrogen atom or a carbon atom, provided that when A1 to A4 are a nitrogen atom, R1 and R11 to R13 connecting to the nitrogen atom do not exist.)
