ABSTRACT:
A protective film for polarizing plate comprising k layers (k is an integer of 2 or more) of thermoplastic resin layer laminated, whereina refractive index ni(380) at a wavelength of 380 nm and a refractive index ni(780) at a wavelength of 780 nm in the i th thermoplastic resin layer as well as a refractive index ni+1(380) at a wavelength of 380 nm and a refractive index ni+1(780) at a wavelength of 780 nm in the i+1 th thermoplastic resin layer have a relationship inin-line-formulae description="In-line Formulae" end="lead"?∥ni(380)−ni+1(380)|−|ni(780)−ni+1(780)∥≦0.02in-line-formulae description="In-line Formulae" end="tail"?(where, i is an integer of 1 to k−1). A polarizing plate is obtained by bonding the protective film for the polarizing plate and a polarizer. And a liquid crystal display comprising the polarizing plate and a liquid crystal panel.
