METHOD FOR PRODUCING POLARIZING PLATE

摘要

PURPOSE: A method for manufacturing a polarizing plate is provided to manufacture the polarizing plate in which optical property and junction strength are excellent by controlling excessive reverse curl. CONSTITUTION: A polarizing film(21) is returned in order to be inserted between an acrylic resin film(25) and a transparent resin film by a material film returning process. The acrylic resin film is attached to one side of the polarizing film by using adhesive of hardening property. The transparent resin film is attached to the other side of the polarizing film by using the adhesive of hardening property. A first junction roll(15) contacts to the acrylic resin film and revolves to a returning direction of the acrylic resin film. A second junction roll(16) contacts to the transparent resin film and revolves to a returning direction of the transparent resin film. The adhesive is hardened.
