| description | The invention belongs to the field of optical films for liquid crystal displays, and particularly relates to an optical diffusion film. The optical diffusion film comprises a transparent base material, a light diffusion layer arranged on the upper surface of the transparent base material and a back layer arranged on the lower surface of the transparent base material, and the back layer is coated with a coating liquid. The coating liquid comprises the following substances in percentage by weight: 0.015% to 0.172% of a leveling agent, 0.549% to 0.686% of an antistatic agent, 2.325% to 3.923% ofanti-adhesion particles, 27.465% to 34.322% of an adhesive resin, 2.059% to 7.427% of a cross-linking agent and 58.838% to 65.916% of a solvent, wherein the leveling agent is an acrylate copolymer. According to the technical scheme, the bonding fastness of the protective film can be effectively considered, and the anti-static effect can be guaranteed.
