摘要:
To provide an organic EL device having low driving voltage, high luminous efficiency, and particularly a long lifetime by combining various materials for an organic EL device having excellent hole and electron injection/transport performances, electron blocking ability, stability in a thin-film state, and durability as materials for an organic EL device having high luminous efficiency and high durability so as to allow the respective materials to effectively reveal their characteristics.
In the organic EL 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 includes an arylamine compound of the following general formula (1) and a radialene derivative of the following general formula (2).
