Disclosed is a polarizing plate protective film that can be bonded to a polarizer at high speed without involving air by using a photocurable adhesive, and has high heat resistance and high adhesion to the polarizer. is there. Moreover, the polarizing plate provided with the said polarizing plate protective film is provided. The polarizing plate protective film has 2.00 ≦ DSac (A) + DSay (A) ≦ 2.90, 1.50 ≦ DSay (A) ≦ 2.80, 1000 ≦ Mw (A) ≦ 80000, 120. Cellulose ester (A) satisfying ≦ Tg (A) ≦ 147 ° C., 2.00 ≦ DSac (B) ≦ 2.90, 100000 ≦ Mw (B) ≦ 300000, 150 ≦ Tg (B) ≦ 190 Cellulose ester (B) is contained, the containing mass ratio exists in the range of 1: 99-30: 70, and the glass transition temperature Tg of a polarizing plate protective film exists in the range of 148-190 degreeC.
