PROBLEM TO BE SOLVED: To provide an organic light emission element which can be used effectively for a flat light source such as a full color display, a back light, or the like, and a light source array such as a printer or the like, which can emit a plurality of kinds of light, which has high brightness and high luminous efficiency, of which it is possible to enlarge the area and suppress power consumption, moreover which is easy to manufacture. SOLUTION: The organic light emission element has a first luminescence layer containing an ortho-metallic complex in the organic luminescence layer which is constituted laminating a transparent electrode, the organic luminescence layer and a back electrode on a substrate, and a second luminescence layer containing a macromolecule luminescent material. A mode is which an ortho- metallic complex is an iridium complex, a mode in which the first luminescence layer of the ortho-metallic complex contains 1 to 20 weight %, a mode in which the first luminescence layer contains a host compound, a mode in which an emission spectrum of the first luminescence layer and an emission spectrum of the second luminescence layer differ, a mode in which the first luminescence layer and the second luminescence layer are formed by a wet film-forming method, or the like, are desirable.
