Abstract: The present invention pertains to a polarizing film having a transparent resin layer on at least one side of a polarizer containing a polyvinyl alcohol-based resin, wherein the transparent resin layer has a thickness of 0.2 μm or more and is formed from a layer-forming material containing a polyvinyl alcohol-based resin having a saponification degree of 96 mol % or more, and wherein the combined total content of sodium acetate and potassium acetate contained in the transparent resin layer is less than 1 wt %. This polarizing film has crack-resistant properties, and can minimize degradation of the optical characteristics in a heating and humidifying test.

Abstract: A surface-protective film attached polarizing film is disclosed which includes a polarizing film (A) having a thickness of 100 μm or less, and a surface-protective film (B) provided on at least one surface of the polarizing film (A), wherein the polarizing film (A) comprises a polarizer, and a protective film provided on at least one surface of the polarizer, the polarizer comprises a polyvinyl alcohol-based resin and has a thickness of 10 μm or less, the polarizing film (A) has a width WA, the surface-protective film (B) has a width WB, a difference between the widths WA and WB (WA−WB) is 3 mm or more, and a peel strength of the surface-protective film (B) to the polarizing film (A) is 0.2 N/25-mm or less. The surface-protective film-attached polarizing film allows to be restrained the polarizing film from being broken, when the surface-protective film is peeled from the polarizing film.
