To provide an organic electroluminescent element with high luminous efficiency, a long life and a small boost of drive voltage.
The organic electroluminescent element is formed by laminating: an anode; a hole injection layer containing a triaryl amine derivative including a triphenyl amine structure as a partial structure, and an electron accepting compound; a hole transport layer containing a polymer with a repeating unit represented by the formula (2); a luminescent layer containing a triaryl triazine derivative including a triphenyl triazine structure as a partial structure, and a phosphorescent body; and a cathode, in this order. (in the formula (2), R1 to R8 represent a silyl group which may be independently replaced by a hydrogen atom, a halogen atom, a cyano group, an alkyl group of carbon numbers 1 to 10, an alkoxy group of carbon numbers 1 to 10, an aryl group of carbon numbers 6 to 20, or an alkyl group of carbon numbers 1 to 10, respectively, and R9 represents an alkyl group of carbon numbers 1 to 10, or an aryl group of carbon numbers 6 to 10.)
