ABSTRACT:
When a polarization plate is manufactured by laminating and laminating at least two types of retarder films onto a polarizer film by a laminating apparatus, with the two films of at least the two types of retarder films and at least the polarizer films being laminated such that the difference in the angle between the feeding directions of the two films is within the range of 40° to 80°. With this arrangement, a good handling property can be obtained, improvement in yield ratio can be expected, and the installation area of the laminating apparatus can be reduced due to a reduction in size of the laminating apparatus.
