PRODUCTION METHOD FOR POLARIZING LAMINATED FILM AND PRODUCTION METHOD FOR POLARIZING PLATE

摘要

Provided are a production method for a polarizing laminated film and a production method for a polarizing plate using the polarizing laminated film obtained using said method. The production method for the polarizing laminated film includes: a step in which a polarizing film comprising a polarizer layer upon a base material film is prepared; and a step in which a first protective film wider than the polarizing film is arranged upon the polarizer layer in the polarizing film via a first adhesive layer, and a second protective film wider than the polarizing film is arranged upon the other surface of the polarizing film. The first and second protective films are arranged such that: both ends in the width direction of the first and second protective films are positioned further on the outside than both ends in the width direction of the polarizing film; and both ends in the width direction of the first adhesive layer are positioned further on the outside than both ends in the width direction of the polarizing film, and further on the inside than both ends in the width direction of the first and second protective films.
