    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 Ar1 to Ar6 are independently a C6-60 aromatic group which does not contain a styryl group nor an alkenyl group, at least one of A, Ar1, Ar2, or B, Ar3 to Ar6 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.
