Abstract
There is provided a light diffusion sheet comprising a light diffusion layer formed on a transparent substrate and containing a binder resin and resin particles that impart an uneven surface, wherein the light diffusion sheet has a total light transmission of 70.0% or more, haze of 80.0% or more, and a distinctness of transmission image of 25.0% or more. This light diffusion sheet is high luminance in the front direction, is excellent in light-diffusing property, does not require use of an expensive prism sheet which is readily susceptible to surface damage, and does not require careful handling.
