    • An organic electroluminescence device comprising: a luminous layer containing a luminous material and a hole transport material, or a luminous layer containing a luminous material and a hole transport layer containing a hole transport material, between a pair of electrodes at least one of which is transparent or translucent, characterized in that the hole transport material contains an aromatic amine selected from the group consisting of compounds represented by the formulae (1) to (4)


      wherein each of Ar₁, Ar₂, Ar₃, Ar₄, Ar₅ and Ar₆ independently represents an aromatic hydrocarbon ring group having six or more carbon atoms or an aromatically heterocyclic compound group having four or more carbon atoms, x represents an integer of 2 or more, and each of A₁, A₂, A₃, A₄, A₅, A₆, A₇, A₈, A₉, A₁₀ and A₁₁ independently represents a group selected from the following formulae (5) to (13) (plural A₁₁s may be the same or different);



      wherein each of R₁ to R₇, R₉ to R₁₁ and R₁₃ to R₁₈ independently represents a member selected from the group consisting of C₁-C₁₂ alkyl and alkoxy groups, C₆-C₁₄ aryl and aryloxy groups, a nitro group and heterocyclic compound groups; when one benzene ring or pyridine ring has plural substituents, they are selected independently; each of R₈ and R₁₂ independently represents a member selected from the group consisting of a hydrogen atom and C₁-C₁₂ alkyl groups; and a, b, c, d, e, f, g, h, i, j, k, l, m, n, o and p represent integers of 0 ≦ a, b, g ≦ 5, 0 ≦ c, d, e, f, h, i, k, m, o, p ≦ 4 and 0 ≦ j, l, n ≦ 3.
