摘要： PROBLEM TO BE SOLVED: To provide a durable and highly reliable high luminance light emitting element having a long light emission life. SOLUTION: The compound has a high melting point and a high glass transition temperature, and a thin film formed by the vapor deposition or the like is transparent, forms a stable amorphous state even at a room temperature or higher, and exhibits smooth and excellent film quality. Thus, a thin film can be formed by itself without using a binder resin. In the organic EL element, since the compound is used in an organic compound layer, especially and preferably in a hole injecting and transporting layer, uniform plane light emission without unevenness is made possible, high luminance is stably obtained over a long period of time, and durability and reliability are excellent.
