POLARIZING PLATE PROTECTION FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a polarizing plate protection film which restrains generation of rainbow-like irregularities and produces a liquid crystal display apparatus of excellent display quality when a commercially-available film is used as it is under commercially-available conditions or when a film produced by a common film forming method is used and further to provide a polarizing plate using the polarizing plate protection film.

SOLUTION: The polarizing plate protection film includes a transparent substrate and a refractive index difference-mitigating part which is formed on the transparent substrate and includes a low refractive index layer at its most outer layer, in which the low refractive index layer includes a refractive index to the light transmitted through the transparent substrate smaller than that of the transparent substrate and bigger than that of the air. In-plane distribution of in-plane retardation (Re) of the transparent substrate is 5 nm or more.
