Abstract:
It is an object to provide a noble anthracene derivative, a light emitting element with a high luminous efficiency, and further a light emitting element with a long lifetime. It is another object to provide a light emitting device and electronic device with a long lifetime by using the light emitting element. An anthracene derivative represented by General Formula (1) is provided. Since the anthracene derivative represented by General Formula (1) has a high luminous efficiency, when the anthracene derivative is used for a light emitting element, the light emitting element can have a high luminous efficiency. Further, when the anthracene derivative represented by General Formula (1) is used for a light emitting element, the light emitting element can have a long lifetime.
