METHOD FOR MANUFACTURING POLARIZER AND POLARIZER USING THEREOF

摘要

A manufacturing method of a polarizing plate and the polarizing plate manufactured using the same are provided to maximize photonic and dyeing efficiency of the polarizing plate. A manufacturing method of a polarizing plate includes the following steps of: swelling a polyvinyl alcohol film of 40 ~ 75mum thickness in a swelling tub in which swelling liquid is filled(S10); dyeing the polyvinyl alcohol film with iodine or dichromatic dye(S20); cross-linking the film with a cross-linking agent(S30); drying the film at temperature of 40 ~ 60°C(S40); and drawing the film with a drawing roller(S50). The polyvinyl alcohol film is a base film of the polarizing plate.
