Abstract
The present invention is a one-side-protected polarizing film having a polarizer and a protective film provided on only one surface of the polarizer, wherein the polarizer contains a polyvinyl alcohol-based resin, has a thickness of 10 μm or less, and is configured so that optical properties represented by a single-body transmittance T and a polarization degree P satisfy the following relationship: P>−(10−1)×100 (provided that T<42.3) or P≥99.9 (provided that T≥42.3), a transparent layer is provided on another surface of the polarizer, and a dynamic friction coefficient of the surface on which the protective film is provided is 0.2 or less. In this one-side-protected polarizing film, it is possible to resist the occurrence of through cracks and nano-slits even when the polarizer has specific optical properties and a thickness of 10 μm or less.
