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 n i (λ) at a wavelength in the range of 380 to 780 nm of the i th thermoplastic resin layer as well as a refractive index n i+1 (λ) at a wavelength in the range of 380 to 780 nm of the i+1 th thermoplastic resin layer have a relationship of ∥n i (λ)−n i+1 (λ)|≦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. |
