    摘要: An optical element laminate is provided and includes a first optical element and a second optical element superimposed with the first optical element. The first optical element and the second optical element are each a rectangular film or sheet. The first optical element has at least two side walls at two opposing sides among four sides of the first optical element and the second optical element has at least two side walls at two opposing sides among four sides of the second optical element.

    摘要: A diffusion sheet includes a light-transmissive substrate, a plurality of structures, and a flat portion. The light-transmissive substrate includes a first main surface, and a second main surface. The plurality of structures have convex shapes and are randomly formed on the first main surface. The flat portion is formed among the plurality of structures on the first main surface and has a surface roughness (Ra) of no less than 0.9 μm.
