ABSTRACT:
The present invention relates to an organic electroluminescent element and a display device exhibiting high emission efficiency and long life. The organic electroluminescent element contains a pair of electrodes having therebetween at least one constituting layer containing a phosphorescent light emitting layer, wherein one of the constituting layer contains a compound represented by Formula (1):wherein Z1represents an aromatic heterocylic ring which may have a substituent; Z2represents an aromatic heterocylic ring or an aromatic hydrocarbon ring both of which may have a substituent; Z3represents a divalent linking group or a single bond; and R101represents a hydrogen atom or a substituent.
