An aromatic amine derivative represented by the following formula (1), wherein at least one of Ar1 to Ar3 is represented by the following formula (2), wherein X1 to X3 are independently a nitrogen atom or CR2, provided that two of X1 to X3 are a nitrogen atom and X1 and X3 are not simultaneously a nitrogen atom.
Provided is an organic electroluminescence device having high luminous efficiency, high heat resistance and an extremely long lifetime. The organic electroluminescence device of the present invention includes an organic thin film layer composed of one or more layers containing at least a light emitting layer is interposed between a cathode and an anode. The light emitting layer includes a compound containing a condensed ring and a luminescent metal complex capable of emitting light having a red-based color. It is preferable that the compound containing a condensed ring includes a host material, while the luminescent metal complex capable of emitting light having a red-based color includes a phosphorescent dopant.
