In an organic electroluminescent element comprising an anode layer, an organic luminescent layer, an inorganic compound layer (or reductive dopant layer) and a cathode layer; the organic luminescent layer comprises an aromatic amine compound of a formula (1), and/or an aromatic amine compound of a formula (2) wherein A, B, and Ar<SUP>1 </SUP>to Ar<SUP>6 </SUP>are independently a C<SUB>6-60 </SUB>aromatic group which does not contain a styryl group nor an alkenyl group, at least one of A, Ar<SUP>1</SUP>, Ar<SUP>2</SUP>, or B, Ar<SUP>3 </SUP>to Ar<SUP>6 </SUP>contains at least three condensed aromatic rings, and p, q and r of a condensation number are an integer of 1 to 6. The element has significantly long half-life and high luminance even at low driving voltages.
