(Problem) Provided is an organic electroluminescent device having high luminous efficiency, excellent blue purity, and small chromaticity change accompanying deterioration of driving. (Solution means) It has a board | substrate, a pair of electrode which is arrange | positioned on the board | substrate, and consists of an anode and a cathode, and is arrange | positioned between this electrode, and at least 1 layer of organic layers containing a light emitting layer, and at least 1 layer of the said organic layer The organic electroluminescent element containing the compound represented by a following formula. (R 1 to R 18 each independently represent a hydrogen atom or a substituent, and at least one of R 1 to R 8 and R 10 to R 17 represents -L-NR 19 R 20 (R 19 and R 20 are each respectively) Independently any of an alkyl group, an aryl group, or a heteroaryl group, R 19 and R 20 may be combined to form a ring, L represents a single bond or a divalent linking group) X 1 to X 18 are each independently When a carbon atom or a nitrogen atom is represented and X 1 to X 18 represent a nitrogen atom, R 1 to R 18 bonded thereto are not present) |
