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): ##STR00001## wherein Z.sub.1
represents an aromatic heterocylic ring which may have a substituent;
Z.sub.2 represents an aromatic heterocylic ring or an aromatic
hydrocarbon ring both of which may have a substituent; Z.sub.3 represents
a divalent linking group or a single bond; and R.sub.101 represents a
hydrogen atom or a substituent.
