Novel anthracene derivatives are provided. Further, a light-emitting element, a light-emitting device, and an electronic appliance each using the novel anthracene derivative are provided. Anthracene derivatives represented by general formulae (G11) and (G21) are provided. The anthracene derivatives represented by the general formulae (G11) and (G21) each emit blue light with high color purity and have a carrier-transporting property. Therefore, each of the anthracene derivatives represented by the general formulae (G11) and (G21) is suitable for use in a light-emitting element, a light-emitting device, and an electronic appliance.
                            提供了新型
