A single-protective polarizing film having a protective film only on one side of a polarizer, wherein the polarizer has predetermined optical characteristics and has a thickness of 10 μm or less, and defects due to through cracks and nano-slits Providing a piece-protecting polarizing film capable of suppressing the above. A single-protective polarizing film having a protective film only on one side of a polarizer, wherein the polarizer contains a polyvinyl alcohol-based resin, has a thickness of 10 μm or less, and has a single transmittance T and polarization. The optical property represented by the degree P is represented by the following formula P> − (100.929T-42.4-1) × 100 (where T <42.3), or P ≧ 99.9 (where T ≧ 42.3) is satisfied, and the other side of the polarizer has a transparent layer and has a dynamic friction coefficient of 0.2 on the surface having the protective film. A single-protective polarizing film characterized by: [Selection] Figure 1 |
