PROBLEM TO BE SOLVED: To provide an organometallic complex with high light emission efficiency which achieves improved color purity by reducing half width of a light emission spectrum, as a new substance having a new skeleton.SOLUTION: An organometallic complex includes, as a ligand, a six-membered ring of a heterocyclic aromatic ring including two or more nitrogen, including a coordinating nitrogen atom, and a β-diketone (in a general formula, X represents a substituted or unsubstituted six-membered heteroaromatic ring including two or more nitrogen atoms, including the coordinating nitrogen atom, and each of Rto Rrepresents a 1-6C alkyl group).SELECTED DRAWING: None |
