POLARIZING FILM PROTECTED ON ONE SIDE, POLARIZING FILM WITH PRESSURE-SENSITIVE ADHESIVE LAYER, IMAGE DISPLAY DEVICE, AND CONTINUOUS PRODUCTION PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/052534
Kind Code:
A1
Abstract:
The present invention is a polarizing film protected on one side and comprising a polarizing element and a transparent protective film disposed on only one surface thereof, wherein the polarizing element includes a poly(vinyl alcohol)-based resin, has a thickness of 10 μm or less, and has been configured so that the optical characteristics represented by the transmittance T of the polarizing element itself and the degree of polarization P satisfy the relationship P>-(100.929T-42.4-1)×100 (where T<42.3) or P≥99.9 (T≥42.3), and the polarizing element has, on the other surface, a transparent layer having a compressive modulus at 80°C of 0.1 GPa or greater. The polarizing film protected on one side, although including a polarizing element which has the given optical characteristics and has a thickness of 10 μm or less, can be inhibited from suffering piercing cracks or nanoslits.
