摘要：
[Object]
An organic electroluminescent device having high efficiency, low driving voltage and a long lifetime is provided by combining various materials for an organic electroluminescent device, which are excellent, as materials for an organic electroluminescent device having high efficiency and high durability, in hole and electron injection/transport performances, electron blocking ability, stability in a thin-film state and 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 injection layer, a first hole transport layer, a second hole transport layer, a light emitting layer, an electron transport layer and a cathode in this order, the second hole transport layer includes an arylamine compound represented by the following general formula (1).
