Disclosed is a polarizer protective film having high heat resistance, high transparency, high optical characteristics and high mechanical strength, which can be formed thin and is excellent in adhesion to a polarizer. Also disclosed is a polarizing plate using such a polarizer protective film and a polarizer. This polarizing plate has high adhesion between the polarizer protective film and the polarizer, while being excellent in optical characteristics and heating/humidification durability. Further disclosed is a high-quality image display using such a polarizing plate. Specifically disclosed is a polarizer protective film which contains an acrylic resin having a specific acrylate structure unit and a specific cyclic structure unit.
