An anti-Newton's ring backlight module and liquid crystal display using the same has a housing, a light guide plate, multiple optical films, an air passage and a adhesive layer. The housing has a top surface, where an internal cavity is formed, and a sidewall having an inner shoulder. The light guide plate is disposed in the internal cavity. The optical films are disposed on the light guide plate and are substantially smaller than the inner shoulder of the internal cavity to define an air passage between the optical films and the inner shoulder. The adhesive layer is bonded to the optical films and the inner shoulder and mainly has at least one through hole corresponding to the air passage and communicates with the air passage to allow air trapped between adjacent optical films to escape away. The release film simplifies the Liquid crystal panel module manufacturing process.
