【Task】
High luminous efficiency, as a material for an organic electroluminescence element having high durability, the hole and electron injecting and transporting performance, an electron blocking ability, various for excellent organic electroluminescent device in stability and durability in a thin film state the material, that the characteristics each material has the combined so effectively expressed, low driving voltage, a high luminous efficiency, and to provide an organic electroluminescence element having a long lifetime.
A
At least an anode, a hole injection layer, a first hole transport layer, the second hole transporting layer, light emitting layer, an organic electroluminescence device having an electron-transporting layer and a cathode in this order, the hole injection layer is represented by the following general formula ( the organic electroluminescent device characterized by containing an arylamine compound and an electron acceptor represented by 1).
[Formula 1]
(Wherein, Ar
1 to Ar
4 may be the same or different, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic, It represents an aromatic group.)
