<p>The problem of the present invention is to obtain excellent adhesiveness between a thin film as a polarizing film and a thin film as a protective film and thereby provide a method for producing a thin film polarizing plate by means of which adhesiveness with the polarizing film is excellent but there is no wrinkling or curling during polarizing plate production, generation of air bubbles due to curling or deformation when the polarizing film panels are bonded, or rise in haze or accompanying reduction in front surface contrast of the liquid crystal display device. The method for producing a polarizing plate of the present invention is a method for producing a polarizing plate whereby a polarizing film (A) having a hydrophilic polymer layer dyed by a dichroic substance and a cellulose ester film (B) are laminated via an adhesive agent on at least one surface of the polarizing film (A), characterized in that the cellulose ester film (B) is subjected to hydrophilization by either plasma treatment or corona treatment, and the surface free energy before and after hydrophilization treatment of the cellulose ester film (B) is a value within a predetermined range.</p> |
