  • THIN FILM POLARIZER, METHOD OF MANUFACTURING THE SAME, AND POLARIZING PLATE AND DISPLAY DEVICE INCLUDING THE SAME
    Publication number: 20150260894
    Abstract: A method of manufacturing a thin film polarizer includes forming a film laminate by alternately bonding two or more non-oriented polymer films and two or more non-oriented polyvinyl alcohol-based films to each other using attractive force or an adhesive layer, orienting the film laminate so that the polyvinyl alcohol-based film has a thickness of 10 ?m or less after the orienting of the film laminate, and separating the polymer films and the polyvinyl alcohol-based films of the oriented film laminate from each other.
