| description | The invention relates to a friction-resistant type light diffusion film and a backlighting device. The light diffusion film comprises a base material, a light diffusion layer and a bonding-resistant layer, wherein the arithmetical mean deviation Ra of the profile and the microscopic roughness height Rz at ten o'clock of the surface of the light diffusion layer meet the following requirements: Ra is greater than or equal to 1mu and less than or equal to 5mu while Rz is greater than or equal to 5mu and less than or equal to 25mu; the arithmetical mean deviation Ra of the profile and the microscopic roughness height Rz at ten o'clock of the surface of the bonding-resistant layer meet the following requirements: Ra is greater than or equal to 0.2mu and less than or equal to 0.5mu while Rz is greater than or equal to 2mu and less than or equal to 7mu. The light diffusion film provided by the invention are prevented from being scratched even if the contact friction is caused among all layer surfaces of the light di |
