The present invention relates to a polarizing film which has a transparent resin layer on at least one surface of a polarizing member having a thickness of 10 μm or less, and the polarizing member contains a polyvinyl alcohol-based resin and is configured to have a monomer transmittance T and The optical characteristic represented by the degree of polarization P satisfies the condition of the following formula: P>-(100.929T-42.4-1)×100 (except T<42.3), or P≧99.9 (except T≧42.3), the transparent resin layer is contained The formation of the transparent resin layer forming material of the aqueous emulsion resin, and the hardness is 0.01 GPa or more. In the case of a polarizing film using a thin polarizing member, the polarizing film of the present invention can suppress the occurrence of defects such as nano-slit, and the optical property is lowered during the heating and humidifying test, that is, has high optical reliability. . |
