(Problem) An object of this invention is to provide the manufacturing method of the polarizing plate which can improve the adhesive force of a polarizer and a cycloolefin resin film, without the appearance defect by a scar, a foreign material, or a scratch. (Solution means) In the manufacturing method of the polarizing plate of this invention, the output intensity is 0.9 to the surface in which the polarizer of a cycloolefin resin film is formed. It includes a step of performing a corona discharge treatment at 2.5 kPa, a step of washing the cycloolefin resin film subjected to the corona discharge treatment, and a step of bonding the polarizer and the cycloolefin resin film through an adhesive agent. |
