摘要：
A diffusion sheet includes a light-transmissive base member, a plurality of structures, and a flattened portion. The light-transmissive base member has a first main surface and a second main surface. The plurality of structures have convex shapes, which are randomly formed on the first main surface. The flattened portion is formed among the plurality of structures on the first main surface and has a surface roughness (Ra) equal to or lower than 0.6 μm.
