ABSTRACT:
An object is to provide a novel organic compound capable of visible light emission. In particular, an object is to provide a novel organic compound that exhibits a broad emission spectrum when it is used for a light-emitting element. In addition, an object is to provide a light-emitting element and a light-emitting device that gives white light emission with an excellent color rendering property. The quinoxaline derivative represented by General Formula (1) is provided. Since the quinoxaline derivative represented by General Formula (1) is capable of emitting visible light, it can be favorably used for a light-emitting element. In particular, since the quinoxaline derivative represented by General Formula (1) exhibits a broad emission spectrum when it is used for a light-emitting element, by using it for a light-emitting element a light-emitting element that gives white light emission with an excellent color rendering property can be obtained.
