摘要:
A material for an organic electroluminescent device that is excellent in hole injection and transport abilities, electron blocking ability, stability in a thin film state, and durability is provided as a material for an organic electroluminescent device having high efficiency and high durability. Further, an organic electroluminescent device having low driving voltage, high efficiency, and a long lifetime is provided by combining the material with various materials for an organic EL device that is excellent in hole and electron injection and transport abilities, electron blocking ability, thin film stability, and durability, in such a manner that the characteristics of the materials can be effectively exhibited. An organic electroluminescent device comprising at least an anode, a hole transport layer, a light emitting layer, an electron transport layer, and a cathode in this order, wherein the hole transport layer comprises an arylamine compound of the following general formula (1).
