摘要：
Provided are an organic electroluminescence device having high current efficiency and a long lifetime, and a biscarbazole derivative for realizing the device. The biscarbazole derivative has a specific substituent. The organic EL device has a plurality of organic thin-film layers including a light emitting layer between a cathode and an anode, and at least one layer of the organic thin-film layers contains the biscarbazole derivative.
