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