| abstract |
An organic electroluminescent device having low driving voltage, high luminous efficiency, and a long lifetime is provided by combining various materials which are excellent in hole and electron injection/transport performances, an electron blocking ability, stability as a thin film and durability for an organic electroluminescent device of high luminous efficiency and high durability, in such a manner that the materials can effectively exhibit characteristics thereof. The organic electroluminescent device includes 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 includes an arylamine compound of the following general formula (1) and an electron acceptor. [Formula 1] In the formula, Ar 1 nto Ar 4 nmay be the same or different, and represent a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted aromatic heterocyclic group, or a substituted or unsubstituted condensed polycyclic aromatic group. |
