Organometallic Complex and Light-Emitting Device

Abstract

A novel organometallic complex and a novel light-emitting device that are highly useful or reliable are provided. The organometallic complex represented by General Formula (G1) is provided. Note that R1, R2, and R4 to R22 each independently represent hydrogen (including deuterium), an alkyl group having 1 to 10 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 18 carbon atoms, at least one of R2 and R4 represents an alkyl group having 1 to 10 carbon atoms, and any one or more of R18 to R22 represent an alkyl group having 3 to 10 carbon atoms or a substituted or unsubstituted aryl group having 6 to 18 carbon atoms.
