Abstract
The surface light emitting device includes an organic EL element, a protection substrate, a protection part, and a light extraction structure part. The element has a first face and a second face opposite to the first face, and emits light from the first face. The substrate has transparency for light emitted from the element, and is placed facing the first face, and has a primary surface facing the first face of the element. The protection part is placed facing the second face of the element, and constitutes a housing in combination with the substrate and accommodates the element so as to protect the element from water. The structure part is interposed between the first face of the element and the substrate, and suppresses reflection of light emitted from the element on at least one of the first face of the element and the primary surface of the substrate.
