Abstract
An organic EL element including an anode and a cathode opposing to each other, and at least a luminescent layer, positioned therebetween, including an aromatic amine derivative designated by a general formula [1] and a dibenzo-{[f,f′]-4,4′,7,7′-tetraphenyl}-diindeno-[1,2,3-cd:1′,2′,3′-lm] perylene derivative designated by a general formula [2]. The organic EL element has the excellent luminescent efficiency, brightness and chromaticity. 1
