摘要：
A benzanthracene derivative having hydrogen atom at the 12-position, and an organic electroluminescence device having an organic thin film layer, which has one layer or a plurality of layers including at least a light emitting layer, is disposed between a cathode and an anode and contains the benzanthracene derivative in at least one layer in the organic thin film layer singly or as a component of a mixture. The electroluminescence device provides a great efficiency of light emission, has a long life and exhibits an excellent chromaticity.
