A backlight module is provided, including a light guide plate, a back plate, a plastic frame, an optical film and a light source. The plastic frame forms a receiving cavity and an accommodation cavity. The light guide plate is mounted in the receiving cavity and located above the back plate. The optical film is mounted in the accommodation cavity and placed on a light exit surface of the light guide plate. The receiving cavity at least includes a vertical end surface and an inclined sidewall. The accommodation cavity at least includes a horizontal support surface and a shading surface. The backlight module and the liquid crystal display of the present invention employ the receiving cavity located above the light guide plate to fix the optical film thereby efficiently shortening the shading surface.
