摘要：
An object is to provide a novel quinoxaline derivative, a light-emitting element with low driving voltage, and a light-emitting element which consumes low power. Another object is to provide a light-emitting device and an electronic appliance which consume low power by using the above light-emitting element. A quinoxaline derivative represented by a general formula (G11) is provided, in which at least one of carbon at a 2-position and carbon at a 3-position of quinoxaline, and carbon at a 2-position of a 1H-benzimidazole ring are bonded to each other via an arylene group.
