PROBLEM TO BE SOLVED: To provide a large area surface light emitting body achieving uniform emission over the whole surface light emitting body by improving the darkness at joints of organic EL light emitting elements in the surface light emitting body including a plurality of organic EL light emitting elements.SOLUTION: A surface light emitting body includes a plurality of organic EL light emitting elements disposed on the light incident surface side of a substrate, and has a diffusion means at a space between the organic EL light emitting elements. Preferably, the diffusion means has a concave surface on a surface that is on the reverse side to the substrate, has an uneven structure on a surface that is on the reverse side to the substrate, or comprises a resin containing fine particles. |
