Abstract
An anti-abrasion optical diffusion film (), an LCD device and a light source using the anti-abrasion optical diffusion film () are disclosed, in order to solve the problem of the prior art that the diffusion particles are abraded or detached in large area, when an optical diffusion thin film receives external force. The anti-abrasion optical diffusion film () includes a substrate () and a diffusion coating (); the diffusion coating () includes diffusion adhesive layer () and diffusion particles (). The variation coefficient of the diameter of the particles is 10-100%. The invention improves the anti-abrasion ability of the optical diffusion thin film.
