Abstract
An organic electroluminescent element including a substrate, a pair of electrodes including an anode and a cathode, disposed on the substrate, and at least one layer of organic layers including a light emitting layer, disposed between the electrodes, in which at least one of the organic layers contains a compound represented by the following general formula: (R1 to R18 each independently represent a hydrogen atom or a substituent, and at least one of R1 to R8 and R10 to R17 represents -L-NR19R20 (R19 and R20 each independently represent any of an alkyl group, an aryl group, a heteroaryl group. R19 and R20 may be combined to each other to form a ring. L represents a single bond or a divalent linking group). X1 to X18 each independently represent a carbon atom or a nitrogen atom, and when X1 to X18 represent nitrogen atoms, R1 to R18 for bonding do not present.)
