<P>PROBLEM TO BE SOLVED: To provide a light diffusion film whose light diffusivity is improved. <P>SOLUTION: The light diffusion film is provided with a light diffusion layer including acrylic resin particles having variation coefficient of 15% or less and resin binder on a transparent substrate, wherein the acrylic resin particles are formed of a monomer mixture containing a monofunctional acrylic monomer and a multifunctional acrylic monomer and composed of cross-linked acrylic resin particles A and cross-linked acrylic resin particles B, the cross-linked acrylic resin particles A are contained at the rate of 50 to 90 pts.wt. and the cross-linked acrylic resin particles B are contained at the rate of 50 to 10 pts.wt., to 100 pts.wt. of the cross-linked resin particles A and the cross-linked acrylic resin particles B in total, and the cross-linked acrylic resin particles A and the cross-linked acrylic resin particles B have the weight percent and average particle size of multifunction acrylic monomers in a specific range. <P>COPYRIGHT: (C)2009,JPO&INPIT |
