Disclosed is an organic electroluminescent element which is excellent with respect to luminous efficiency, driving voltage and durability and rarely undergoes the deterioration in efficiency during high-luminance driving, and in which the luminescent chromaticity of the element hardly depends on the thickness of a layer that is arranged between a light-emitting layer and a cathode and contains a compound having electron-transporting properties. Specifically disclosed is an organic electroluminescent element which comprises, on a substrate, a pair of electrodes composed of an anode and a cathode and a light-emitting layer arranged between the electrodes, and additionally comprises at least one organic layer arranged between the light-emitting layer and the cathode, wherein the light-emitting layer contains, for example, a compound (A-1), and the at last one organic layer arranged between the light-emitting layer and the cathode contains, for example, a compound (e-1). |
