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.
