Organic compound, benzoxazole derivative, and light-emitting element, light-emitting device, and electronic device using the benzoxazole derivative

摘要

Novel benzoxazole derivatives are provided to reduce driving voltage of light-emitting elements, and to reduce power consumption of light-emitting elements, light-emitting devices, and electronic devices. A benzoxazole derivative represented by the general formula (G1) is provided. Since the benzoxazole derivative represented by the general formula (G1) has an electron-injecting property, the benzoxazole derivative can be suitably used for light-emitting elements, light-emitting devices, and electronic devices.;
