摘要: Disclosed is an organic electroluminescent element which excellent with respect to luminous efficiency and driving voltage rarely undergoes initial luminance drop. Specifically disclosed comprises, on a substrate, pair of electrodes composed anode cathode light-emitting layer arranged between the electrodes, additionally comprises at least one cathode, where in contains, for example, compound (A-1), (e-4).
