Abstract: An optical sheet includes a light scattering layer that scatters at least a part of light incident thereon by diffraction and that includes first and second areas. Each first area is a projection. Each second area is a recess. Each of at least the projections or the recesses has a tapered shape. When a center wavelength of the light incident on the light scattering layer is λ and a refractive index of a layer that is in contact with the light scattering layer at a light emission side is n, spatial frequency components of a pattern formed by the first and second areas have a maximum peak at a spatial frequency in a range of 0.068/(λ×n) or more and 2.8/(λ×n) or less.
