Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an organic light-emitting layer component while having an excellent characteristic.SOLUTION: Improved electroluminescence efficiency of an organic light emitting diode is obtained by using a light emitting layer having an organic metal complex of a transition metal of a formula of LMX (in the formula, L and X are different bidentate ligand). A compound in this formula can be more easily compounded than a conventional method, and an insertion of a fluorescence molecular into a phosphorescent complex and a ligand for finely adjusting a luminescent color and trapping a carrier can be performed by freely selecting a compound.SELECTED DRAWING: None 【課題】優れた特性を有する有機発光層用組成物を提供する。【解決手段】有機発光ダイオードの改良されたエレクトロルミネッセンス効率が、式Ｌ2ＭＸ（式中、Ｌ及びＸは異なる二座配位子である）の遷移金属の有機金属錯体を含有する発光層を用いて得られる。この式の化合物は、従来の方法によるものよりも一層容易に合成することができ、合成の自由な選択により燐光錯体中への蛍光分子の挿入、発光色の微細な調節をするための配位子及びキャリヤーをトラップするための配位子の挿入を行うことができる。【選択図】なし
