ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

An organic electroluminescent element comprising an anode layer, an organic luminescent layer, an inorganic compound layer (or a layer containing a reducible dopant), and a cathode layer, wherein the organic luminescent layer comprises an aromatic amine compound represented by the general formula (1) and/or an aromatic amine compound represented by the general formula (2). (Symbols A, B, and Ar<1> to Ar<6> each independently represents a C6-60 aromatic group containing neither styryl nor alkenyl, provided that at least one of A, Ar<1>, and Ar<2> or of B and Ar<3> to Ar<6> is a group comprising a fused aromatic ring system comprising three or more rings; and p, q, and r, each indicates the number of molecules condensed, each is an integer of 1 to 6.) Due to the constitution, the organic electroluminescent element has an extremely long half-value period and has a high luminance even at a low operating voltage.
