Title: METHOD FOR MANUFACTURING THIN POLARIZER, AND THIN POLARIZER AND POLARIZING PLATE MANUFACTURED USING SAME
Abstract:
The present invention relates to a method for manufacturing a thin polarizer, comprising the steps of: forming a film laminate by adhering an unstretched polyvinyl alcohol-based film by means of an attractive force or an adhesive layer between at least two unstretched polymer films; stretching the film laminate so that the polyvinyl alcohol-based films have a thickness of 10 μm or less after the stretching; and separating the polymer films and the polyvinyl alcohol-based films from the stretched film laminate.
