POLARIZER PROTECTIVE FILM, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a polarizer protective film capable of solving a problem in which a displayable color varies depending on a viewing angle in a recent liquid crystal display element.

SOLUTION: A polarizer protective film contains a thermoplastic resin and fine particles. And the polarizer protective film has a diffusivity (that is a ratio of 30° emitted light to 0° emitted light when incident light comes from the direction that is normal to the polarizer protective film as measured by a goniometer) of 0.3% or less and wavelength selectivity of rectilinearly advancing light shown by formula 1 of 1.001 to 1.600. Formula 1: wavelength selectivity of rectilinearly advancing light=((transmittance for rectilinearly advancing light of 685 nm light)/(total transmittance for 685 nm light))/((transmittance for rectilinearly advancing light of 470 nm light)/(total transmittance for 470 nm light)).
