Abstract
A method for producing a laminated film includes continuous roll to roll production steps of: providing a first long polymer film and having an absorption axis in the transverse direction; providing a second long polymer film and having a slow axis in the machine direction (MD direction); and laminating the polarizing film on the retardation film by adhering the polarizing film to the retardation film with an adhesive layer so that an MD direction of the first long polymer film corresponds to the MD direction of the second long polymer film.
