Film used for manufacturing brightness enhancement film

The invention discloses a film used for manufacturing a brightness enhancement film. The film comprises a transparent base material and adhesion layers, wherein the two surfaces of the base material are coated with the adhesion layers. An anti-sticking layer is arranged on one adhesion layer, hard particles with the particle size ranging from 1 micron to 10 microns and soft particles with the particle size ranging from 1.5 microns to 20 microns are randomly distributed in the anti-sticking layer, and the weight ratio of the hard particles to the soft particles is 10:1-2:1. By combining the hard particles with the soft particles and controlling the particle sizes, problems existing when the hard particles and the soft particles are independently used are solved, a brightness enhancement layer can be protected against scratches when the brightness enhancement film is manufactured, no fingerprint will be left when the brightness enhancement film is inspected, the yield in production of the brightness enhancement film can be significantly increased, and the haze of the product can be guaranteed. Thus, the film can be widely applied to the field of brightness enhancement films.
