Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composition for an organic light-emitting layer having excellent characteristics. SOLUTION: The composition contains a compound of formula L2MX (wherein L and X are distinct monoanionic bidentate ligands; M is a metal forming an octahedral complex; the L-ligand coordinates with M through an sp2hybridized carbon and a hetero atom; M has an atomic number larger than 40, and selected from Sb, transition metals of the second series in the periodic table and transition metals of the third series in the periodic table; and the X-ligand is an O-O ligand or N-O ligand).
