POLARIZER PRODUCTION DEVICE, POLARIZER PRODUCTION METHOD AND POLARIZER

摘要

PROBLEM TO BE SOLVED: To provide a polarizer production device, a polarizer production method, capable of preventing foreign matter adhesion to an optical film, and a polarizer produced by the same method.SOLUTION: The invention discloses a polarizer production device, and a polarizer production method for supplying an optical film to a joint nip roll side, so as to form 0 degree or a sharp angle with respect to an opposite direction of a gravity direction, when a polarization film and the optical film are jointed by the joint nip roll, and a polarizer produced by the same production method. According to the invention, foreign matter adhesion which may be included in a polarizer to the optical film can be prevented, and a proportion defective of the polarizer is reduced and production efficiency is improved.SELECTED DRAWING: Figure 1
