Patent ID: 7955466

Claim:
A method of manufacturing a polarization plate in which at least two types of retarder films are laminated onto a polarizer film to form a product polarizer, comprising the steps of: feeding a polarizer film from a roll in a first feed direction; feeding at least two retarder films in a feed direction different from the first feed direction; stopping the feeding of the polarizer film and the at least two retarder films when they reach a predetermined position and a relative angle difference in the feed directions of the polarized film and the at least two retarder films is in the range of 40-80°; forming a laminate of the polarizer film and the at least two retarder films at the predetermined position; punching out only the at least two retarder films at the predetermined position within the width of the polarizer film to form the product polarizer and contiguous portions of the remaining at least two retarder films; winding the product polarizer into a roll; and winding the contiguous portions of the remaining at least two retarder films into a roll.
