                            The present invention provides a blue or green phosphorescent organic electroluminescent device which has high luminous efficiency. An organic electroluminescent device includes a light-emitting layer containing a pyrroloindole compound represented by general formula (1) below.
In general formula (1), X represents a substituted or unsubstituted arylene group, Ar
1
and Ar
2
each represent a substituted or unsubstituted aryl group, and R
1
to R
8
each represent a hydrogen atom or an alkyl group having 1 to 2 carbon atoms.
