A polarizing film containing a polyvinyl alcohol film containing an iodine-based dichroic dye was produced, the degree of polarization was 99.5% or more, and the following formulas (1) and (2) were satisfied. This polarizing film has good polarization performance and hue, and also has low shrinkage stress and excellent dimensional stability. B≤3.0(1), B+0.035A≤3.9(2). Here, A is the shrinkage stress (N/mm 2 ) of the polarizing film after heating at 80° C. for 4 hours, and B is the monomer b value of the polarizing film. |
