The present invention provides a novel organometallic complex. The organometallic complex is represented by the general formula (G1), and includes a central metal, a first ligand and a second ligand. The first ligand and the second ligand are cyclometallated ligands. At least one of the first ligand and the second ligand includes a substituted or unsubstituted aryl group as a substituent. In the general formula (G1), R1 to R15 independently represent hydrogen, halogen, substituted or unsubstituted alkyl with 1 to 6 carbon atoms, substituted or unsubstituted aromatic with 6 to 13 carbon atoms Any of the group, substituted or unsubstituted heteroaryl group having 3 to 12 carbon atoms. Note that at least one of R1 to R15 represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms. |
