A One-sided protection polarizing film, a polarizing film with an adhesive layer, an image display device, and a continuous production method for the same
Document Type and Number:
Japanese Patent JP6077618
Kind Code:
B2
Abstract:
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-based resin, has a thickness of 10 μm or less, and is designed to have a single-body transmittance T and a polarization degree P representing optical properties satisfying the condition of the following formula: P>−(100.929T−42.4−1)×100 (provided that T<42.3) or P≥99.9 (provided that 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 elastic modulus thereof at 80° C. is C (GPa). Even when the polarizer has prescribed optical properties and the thickness is 10 μm or less, this one-side-protected polarizing film is capable of suppressing through cracks and nano-slits.
