摘要： An organic light-emitting device having a compound represented by the following general formula in a light-emitting layer thereof has a high light emission efficiency. R1 to R5 each independently represent a hydrogen atom or a substituent having a Hammett σp value of 0 or more. R6 to R20 each independently represent a hydrogen atom or a substituent, provided that at least one of R6 to R20 represents a substituted or unsubstituted N,N-diarylamino group. m represents 1 or 2.
