PROBLEM TO BE SOLVED: To provide a method for manufacturing a polarizing plate capable of significantly suppressing a reduction in yield due to the blocking failure of a cellulose acetate-based resin film in manufacturing a polarizing plate by bonding the cellulose acetate-based resin film to a polarizing film.SOLUTION: There is provided a method for manufacturing a polarizing plate in which a polarizing film 1 composed of a polyvinyl alcohol-base resin and a cellulose acetate-based resin film 2 bonded to the polarizing film are conveyed in the same direction to be bonded to each other via an adhesive to form a laminate 4, and then the adhesive is cured to manufacture a polarizing plate 5, wherein the cellulose acetate-based resin film 2 is subjected to heat treatment at a temperature of 80 to 150°C, for example, in a hot air oven 10 and then is superposed on the polarizing film 1 via an adhesive. |
