Abstract

The present invention generally relates to optical films useful in the manufacture of polarizer plates, an improved method for producing polarizing plates, and a Liquid Crystal Display employing the same. More particularly, the invention relates to an optical film composite comprising a temporary carrier substrate having a center area and an edge area, said substrate having coated thereon an optical film wherein the adhesive strength between the optical film and the substrate is greater at the edge area than at the center area of the substrate.
