description [Object] An organic electroluminescent device having high luminous efficiency, low driving voltage, and particularly a long lifetime is provided by combining various materials for an organic electroluminescent device, which have excellent hole and electron injection/transport performances, electron blocking ability, stability in a thin-film state, and durability as materials for an organic electroluminescent device having high luminous efficiency and high durability so as to allow the respective materials to effectively reveal their characteristics. [Means of Realizing the Object] In the organic electroluminescent device having at least an anode, a hole transport layer, a light emitting layer, an electron transport layer and a cathode in this order, the hole transport layer includes an arylamine compound represented by the following general formula (1), and the light emitting layer includes an amine derivative of the following general formula (2) having a condensed ring structure.
