An organic EL element includes an organometallic complex including a rhenium atom; one ligand which has a coordinated nitrogen atom and a coordinated oxygen atom, each coordinated with the rhenium atom, and has at least one π conjugation part; and the other ligand coordinated with the rhenium atom in such a way that the ligand saturates the coordination number of the rhenium atom and the charge of the whole organometallic complex is neutral. |
