【Task】 As a material for organic electroluminescence devices with high luminous efficiency and durability, various materials for organic electroluminescence devices with excellent hole and electron injection / transport performance, electron blocking ability, and stability and durability in thin film state To provide an organic electroluminescence device having a low driving voltage, a high luminous efficiency, and a long life by combining materials so that the characteristics of each material can be effectively expressed. [Solution] In an organic electroluminescence device having at least an anode, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and a cathode in this order, the hole injection layer is an arylamine compound represented by the following general formula (1) And an organic electroluminescence device comprising an electron acceptor. [Chemical 1] (In the formula, Ar 1 to Ar 4 may be the same as or different from each other, and are a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic ring. Represents an aromatic group.) |
