PROBLEM TO BE SOLVED: To provide a polarizing plate used for a liquid crystal display device or the like without deteriorating the polarizing performance, improving the adhesion between a polarizing element and a polarizing plate protective film, and improving productivity. Provided is a polarizing plate protective film that can be improved. SOLUTION: The polarizing plate is formed by bonding a polarizing plate protective film 2 to both surfaces of a polarizing element 1 with an adhesive. The polarizing plate protective film 2 has a moisture permeability of 3 to 10 g / m 2 · 24 hr, 25 ° C., 60% RH parallel water content of 0.01 to 1.5% Contains 80% or more of a cellulose ester, 1 to 20% of a hydrophobic plasticizer, and 0.001 to 5% of a deterioration inhibitor. |
