Abstract:
Provided is a material for an organic electroluminescence device, which is composed of a compound having a specific structure; and is capable of providing an organic electroluminescence device having a high luminous efficiency, excellent heat resistance, and a long lifetime while having no pixel defects, and an organic electroluminescence device using the same. The organic electroluminescence device comprises an organic thin film layer composed of one or more layers including at least a light-emitting layer and sandwiched between a cathode and an anode. In the organic electroluminescence device, at least one layer of the organic thin film layer comprises the material for an organic electroluminescence device.
