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.
提供一种新型喹喔啉衍生物,具有低驱动电压的发光元件,以及消耗低功率的发光元件是一个目标。另一个目标是通过使用上述发光元件来提供一个低功耗的发光装置和电子设备。提供了一种由通用式(G11)表示的喹喔啉衍生物,其中至少在喹喔啉的2位碳和3位碳,以及1H-苯并咪唑环的2位碳之间通过芳基基团相互键合。
