Polarizer protective film

A polarizer protective film which is a multilayer film having a polyester-based resin layer comprising a fluorene-based polyester resin, and acrylic resin layer comprising an acrylic resin, and

• being formed by drawing, wherein
• a thickness ratio of the polyester-based resin layer to the whole is 1 to 30%,
• phase difference Rth(589) in a thickness direction at a wavelength of 589 nm is −50 nm or more and 50 nm or less, and
• in-plane phase difference Ro(550) at a wavelength of 550 nm is 0 nm or more and 50 nm or less.
