Claim 0:
1. An organic light-emitting device containing both a compound having one or more structures represented by the following general formula (1), and a compound represented by the following general formula (2a):, wherein ring a, ring b and ring c each independently represent a benzene ring that may be condensed with any other ring to form an aryl ring or a heteroaryl ring, and at least one hydrogen atom in these rings may be substituted; R1 and R2 each independently represent a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group bonding via the benzene ring; R1 may bond to the carbon atom neighboring to the bonding position (atom) to N in ring a and/or ring c via —O—, —S—, —C(—Rc1)2— or a single bond; R2 may bond to the carbon atom neighboring to the bonding position (atom) to N in ring a and/or ring b via —O—, —S—, —C(—Rc2)2— or a single bond; Rc1 and Rc2 each independently represent a hydrogen atom or an alkyl group;, wherein R41 to R44, and R46 to R49 in general formula (2a) each independently represent a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group, a substituted or unsubstituted diarylamino group, a substituted or unsubstituted diheteroarylamino group, a substituted or unsubstituted arylheteroarylamino group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, or a substituted or unsubstituted aryloxy group, but all four substituted or unsubstituted carbazol-9-yl groups bonding to benzonitrile in general formula (2a) are not the same; n41 to n44, and n46 to n49 each independently represent an integer of any of 0 to 4; and R45 represents a hydrogen atom, a substituted or unsubstituted aryl group, a substituted or unsubstituted carbazol-9-yl group, or a cyano group.
