    Abstract: As a novel substance having a novel skeleton, an organometallic complex having high emission efficiency and improved color purity is provided. The color purity is improved by reducing the half width of an emission spectrum. The organometallic complex is represented by General Formula (G1). In General Formula (G1), at least one of R1 to R4 represents a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms, and the others each independently represent hydrogen or a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms. Note that the case where all of R1 to R4 represent alkyl groups each having 1 carbon atom is excluded. Further, R5 to R9 each independently represent hydrogen or a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms.

    Abstract: A novel organic compound is provided. That is, a novel organic compound that is effective in improving the element characteristics and reliability is provided. An organic compound has a benzonaphthofuran skeleton and a triazine skeleton and is represented by General Formula (G1) below. (In the formula, Ar1, Ar2, and Ar3 separately represent a substituted or unsubstituted phenylene group, and each of m and n is independently 0 or 1. R1 and R2 separately represent hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted methylfluorenyl group, a substituted or unsubstituted dimethylfluorenyl group, a substituted or unsubstituted spirofluorenyl group, a substituted or unsubstituted naphthyl group, or a substituted or unsubstituted phenanthrenyl group. B1 to B3 separately represent nitrogen or carbon, and at least one of B1 to B3 represents nitrogen. In addition, A is represented by General Formula (G1-1). Any one of R3 to R12 is bonded to Ar1, and the others separately represent hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted methylfluorenyl group, a substituted or unsubstituted dimethylfluorenyl group, a substituted or unsubstituted spirofluorenyl group, a substituted or unsubstituted naphthyl group, or a substituted or unsubstituted phenanthrenyl group. Furthermore, Q represents S or O.)
