ORGANIC ELECTROLUMINESCENT ELEMENT, MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENT, AND LIGHT EMITTING DEVICE, DISPLAY DEVICE AND ILLUMINATION DEVICE EACH USING ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescent element capable of realizing a high blue color purity, enhancing the luminous efficiency, and improving reduction of the chromaticity change during driving of the organic electroluminescent element.

SOLUTION: The organic electroluminescent element comprises: a substrate; a pair of electrodes disposed on the substrate and including an anode and a cathode; and at least one organic layer disposed between the electrodes and including a light emitting layer. The organic layer includes a compound represented by the specified formula, where: R1to R12each independently represent a hydrogen atom or a substituent, which may be bound to each other to form a non-aromatic ring; Z1to Z4each independently represent a hydrogen atom or a substituent, where Z1and Z2as well as Z3and Z4may be bound to each other to form a ring.
