摘要：
A diffusion sheet includes: a substrate having a first principal surface and a second principal surface; and structures each in a convex shape formed randomly on the first principal surface or the second principal surface of the substrate. The structures have an identical or almost identical height. The structures have an aspect ratio h/r, where r denotes an average radius of the structures and h denotes an average height of the structures, of more than 0.85 and not more than 1.50. The structures have a filling factor of not less than 60% and not more than 80%.
