ABSTRACT:
An object is to provide a novel anthracene derivative. Another object is to provide a light-emitting element with high luminous efficiency. Yet another object is to provide a light-emitting element with a long lifetime. Still another object is to provide a light-emitting device and an electronic device having a long lifetime by using the light-emitting elements of the present invention. The anthracene derivative represented by General Formula (1) is provided. The ability of the anthracene derivative represented by General Formula (1) to exhibit high luminous efficiency allows the production of a light-emitting element with high luminous efficiency and a long lifetime.
