Abstract:
Provided are an aromatic amine compound as represented by formula (1), used for improving light extraction efficiency and color purity of an organic light-emitting element, an organic light-emitting element material containing the aromatic amine compound, an organic light-emitting element covering layer material containing the aromatic amine compound, and an organic light-emitting element containing the aromatic amine compound. The organic light-emitting element achieves high light-emitting efficiency and color reproducibility. The organic light-emitting element can be used as organic EL display, backlight source for liquid crystal display, illumination, light source for measurement devices, indication board or identification lamp etc. The organic light-emitting element significantly improves light extraction efficiency and has superior color purity.
