Zusammenfassung:An organometallic complex having an emission peak in a long wavelength region (a visible region having a wavelength of 700 nm or greater or a near-infrared region) is provided. The organometallic complex has a structure represented by General Formula (G1), in which a ligand having a quinoxaline skeleton is coordinated to a central metal, and an electron-withdrawing group (e.g., fluorine, a cyano group, a trifluoromethyl group, a trifluoromethylsulfonyl group, or a pentafluorosulfanyl group) is included as a substituent at at least one substitutable position of the benzene ring of the quinoxaline skeleton of the ligand.
