Protective Film for Polarizing Plate

摘要

A protective film for polarizing plate made by laminating k layers (k is an integer of 2 or more) of thermoplastic resin, in which a refractive index ni(lambda) at a wavelength in the range of 380 to 780 nm of the i th thermoplastic resin layer as well as a refractive index ni+1(lambda) at a wavelength in the range of 380 to 780 nm of the i+1 th thermoplastic resin layer have a relationship of ∥ni(lambda)-ni+1(lambda)|<=0.05 (where, i is an integer of 1 to k-1); and a polarizing plate comprising a laminate the protective film for polarizing plate and a polarizer.
