摘要： The present invention provides a composition containing an organic compound AB and an organic compound AA different from the organic compound AB. The organic compound AB is represented by the following general formula [1] and has a fused polycyclic structure A with two or more rings and a ring structure B different from the fused polycyclic structure A. The organic compound AA has the fused polycyclic structure A and is represented by the following general formula [2].

        A-B     [1]



In general formulae [1] and [2], each of the fused polycyclic structures A may have, as a substituent, a deuterium atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group.
