摘要: An organic light-emitting device having a light-emitting layer containing a compound represented by the general formula below has a high light emission efficiency. In the general formula, at least one of R1 to R5 represents a cyano group, at least one of R1 to R5 represents a 9-carbazolyl group, a 1,2,3,4-tetrahydro-9-carbazolyl group, a 1-indolyl group or a diarylamino group, and the balance of R1 to R5 represents a hydrogen atom or a substituent.
