The present invention provides an organic electroluminescence device which: brings physical properties, that is, a low ionization potential, large band gap energy, high injection efficiency, and a high mobility into balance in an excellent manner; has high heat resistance; and shows high current efficiency and a long lifetime while maintaining good luminanoe/voltage characteristics and good current density/voltage characteristics, and a novel amine-based compound for realizing the device. The amine-based compound is of a specific structure containing a quinoxaline ring. The organic electroluminescence device includes an organic thin film layer composed of one or more layers including at least a light emitting layer, the organic thin film layer being interposed between a cathode and an anode. In the organic electroluminescence device, at least one layer of the organic thin film layer contains the amine-based compound alone or as a component of a mixture. |
