PROTECTIVE FILM FOR POLARIZING PLATE

摘要

A protective film for polarizing plate comprising k layers ( k is an integer of 2 or more) of thermoplastic resin layer laminated, wherein
a refractive index n i (380) at a wavelength of 380 nm and a refractive index n i (780) at a wavelength of 780 nm in the i th thermoplastic resin layer as well as a refractive index n i+1 (380) at a wavelength of 380 nm and a refractive index n i+1 (780) at a wavelength of 780 nm in the i+1 th thermoplastic resin layer have a relationship in €– n 1 380 - n i + 1 380 �¢ - �¢ n i 780 - n i + 1 780 €– ‰ 0.02 (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.
