In a new packaging method for light management films in displays, such as liquid crystal displays, a stack of two or more optical films is held together before insertion into the display frame. The stack includes at least two of the films that are adhered together using adhesive positioned outside the viewing area of the films. In some embodiments, the adhesive is provided at one or more tabs provided around the periphery of the film stack.
