Abstract

An anthracene derivative is disclosed, and a light-emitting element, a light-emitting device, an electronic device, and a lighting device using the anthracene derivatives are demonstrated. The structure of the anthracene derivative is described in detail in the specification. The use of the anthracene derivative enables the production of a blue emissive light-emitting element having high emission efficiency, excellent purity of emission color, and a long lifetime, which contributes to the production of a high-performance light-emitting device, electronic device, and lighting device.
