Abstract: The present invention pertains to a polarizing film having a transparent layer on at least one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin and has a thickness of 15 μm or less; the transparent layer-side of the polarizer has a compatible layer thereon having compatibility with the transparent layer; and the thickness A of the polarizer and the thickness B of the compatible layer satisfy the general formula (100×B/A)≧1. This polarizing film has crack resistance and suppresses changes in the dimensions of the polarizer.

Abstract: The pressure-sensitive-adhesive-layer-attached polarizing film of the present invention has, in this order, a polarizer containing a polyvinyl alcohol-based resin, a transparent resin layer containing a polyvinyl alcohol-based resin, and a pressure-sensitive adhesive layer, wherein the pressure-sensitive adhesive layer is formed from a pressure-sensitive adhesive composition containing at least 0.1 parts by weight of an alkali metal salt with respect to 100 parts by weight of a base polymer, and satisfying the general expression (Y/X)≦3, where X is the abundance ratio of the alkali metal salt in a center part in the thickness direction of the pressure-sensitive adhesive layer, and Y is the abundance ratio of the alkali metal salt in the interface between the pressure-sensitive adhesive layer and the transparent resin layer. In the pressure-sensitive-adhesive-layer-attached polarizing film, the anchoring power of the transparent resin layer and the pressure-sensitive adhesive layer is good, and the antistatic function of the pressure-sensitive adhesive layer is also good.
