Abstract
A transparent support and plural types of particle groups having different particle size distributions each other that are to be contained in a light diffusing layer are provided. a blending ratio of the plural types of particle groups is computed such that a space packing ratio of respective particles in the light diffusing layer becomes a specified space packing ratio and the plural types of particle groups having been blended in the computed blending ratio are dispersed on the transparent support, whereby the light diffusing layer is formed on the transparent support. Thus, a diffusion film can be produced simply and at low cost.
