Abstract: PURPOSE: A foaming resin film for light diffusion is provided to have the shielding security and the brightness improvement effect by controlling the density of porosity layer on the surface of the foamed sheet and forming the inner void or size to a desired size. CONSTITUTION: A foaming resin film for light diffusion (10) is formed with a foam layer (13) inside a thermoplastic polymer resin film (11). The foam layer is formed on both sides along the surface of the film. The depth of the foam layer is 40% or less of the total thickness of film from the surface. Bubbles (12) forming the foam layer has 50-130 micron of an average diameter. The brightness degradation rate of the film is 5% or less in comparison with a sheet with the same thickness and no foam layers. A light diffusing film comprises the foaming resin film for light diffusion and a light diffusing coating layer laminated on the film.
