Provided is an organometallic complex which emits light with a short wavelength and has high emission efficiency and high heat resistance. The organometallic complex includes a central metal; and a first ligand, a second ligand, a third ligand, and a fourth ligand which are coordinated to the central metal. The first ligand includes a triazole skeleton including nitrogen bonded to the central metal. The second ligand includes an indolo[3,2-b]carbazole skeleton whose 6-position is bonded to the central metal or a pyrido[2,3-b:6,5-b′]diindole skeleton whose 6-position is bonded to the central metal. The third ligand includes a benzene skeleton whose carbon is bonded to the central metal. The fourth ligand includes a pyridine skeleton whose nitrogen is bonded to the central metal or a benzene skeleton whose carbon is bonded to the central metal.
