ONE-SIDE-PROTECTED POLARIZING FILM, ADHESIVE-LAYER-EQUIPPED POLARIZING FILM, IMAGE DISPLAY DEVICE, AND METHOD FOR CONTINUOUSLY PRODUCING SAME

摘要

The present invention pertains to a one-side-protected polarizing film having a transparent protective film on only one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol resin, has a thickness of 10μm or less, and is configured in a manner such that the optical properties thereof, represented by the single-body transmittance T and the degree of polarization P, satisfy the condition of P>-(100.929T-42.4-1)×100 (however, T<42.3) or P≥99.9 (however, T≥42.3); and the other surface of the polarizer has a transparent layer thereon satisfying formula 1 (F≥3) and formula 2 (C≥e-0.7F), given that the thickness thereof is F (μm) and the compressive elasticity modulus thereof at 80°C is C (GPa). Even when the polarizer has prescribed optical properties and the thickness is 10μm or less, this one-side-protected polarizing film is capable of suppressing the occurrence of through-cracks and nanoslits.
