AROMATIC AMINE COMPOUND, LIGHT-EMITTING ELEMENT MATERIALS AND LIGHT-EMITTING ELEMENT

摘要

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 said aromatic amine compound, an organic light-emitting element covering layer material containing said aromatic amine compound, and an organic light-emitting element containing said 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 a backlight source or illumination for an organic EL display or a liquid crystal display, or as a light source, indication board or identification lamp etc. for devices such as meters. The organic light-emitting element significantly improves light extraction efficiency and has superior color purity.
