Zusammenfassung:	A light guide plate with optical performance protection film, a back light module and an assembly method thereof are disclosed. The light guide plate has a protect film which is provided on a surface of the light guide plate. The protect film includes an adhesive layer, a reflective coating layer and a protective layer. The adhesive layer is adhesively attached to the surface and contains an air medium. The reflective coating layer is provided between the adhesive layer and the protective layer. Wherein, the adhesive layer is added with a foaming agent so that the adhesive layer contains at least 90% of the air medium. A light bar corresponding to a light incident surface of the light guide plate can be used as a back light module, and the light guide plate and the protective film can be assembled together during assembling process to improve the assembly efficiency. Therefore, the light usage can be increased because of the light emitted by the surface will be reflected back to the interior of light guide pl
