Disclosed is an organic electroluminescent device (organic EL device) which is improved in luminous efficiency, fully secured of driving stability, and of simple constitution. Also disclosed is a compound useful for the fabrication of said organic EL device. The organic electroluminescent device comprises organic layers including a light-emitting layer disposed between an anode and a cathode which are piled one upon another on a substrate and at least one of said organic layers comprises a compound for an organic EL device represented by general formula (1). Said organic layer is preferably a light-emitting layer containing a phosphorescent dopant. In general formula (1), X is a substituted or unsubstituted methine group or a nitrogen, Ar

and the nitrogen to which Ar
4
and Ar
5
are joined or Ar
6
, Ar
7
and the nitrogen to which Ar
6
and Ar
7
are joined may together form a nitrogen-containing heterocyclic ring.
