Zusammenfassung:PROBLEM TO BE SOLVED: To provide a surface light-emitting module capable of significantly increasing an apparent light emitting region while keeping a thin thickness.SOLUTION: A surface light-emitting module 1 includes a surface light emitter 20 including an electroluminescent layer 24, a light transmissive base material 10, and a scattering surface 30a. The surface light emitter 20 has a main surface 20a in contact with the light transmissive base material 10 and covered by the light transmissive base material 10. The main surface 20a has a light emitting region A1 as a region where an electroluminescent layer 24 is positioned, and a non-light emitting region A2 where the electroluminescent layer 24 is not positioned. The scattering surface 30a is disposed over a range wider than the light emitting region A1. A bright part E having a brightness on the main surface 20a of 1.25×Lor more is disposed in the light emitting region A1 along an outer peripheral edge of the light emitting region A1, when brightness of a central portion C of the light emitting region A1 on the main surface 20a is L.SELECTED DRAWING: Figure 2 【課題】厚みを薄く保ちつつ、見掛け上の発光領域の大きさを大幅に拡大することができる面発光モジュールを提供する。【解決手段】面発光モジュール1は、電界発光層24を含む面発光体20と、光透過性基材10と、散乱面30aとを備える。面発光体20は、光透過性基材10に接するとともに光透過性基材10によって覆われた主表面20aを有し、当該主表面20aには、電界発光層24が位置する領域である発光領域A1と、発光領域A1の周囲に位置し、電界発光層24が位置しない領域である非発光領域A2とが設けられる。散乱面30aは、発光領域A1よりも広い範囲にわたって配置される。主表面20a上における発光領域A1の中央部Cの輝度をLCとした場合に、主表面20a上における輝度が1.25×LC以上である明部Eが、発光領域A1の外周縁に沿って発光領域A1に設けられる。【選択図】図2
