Abstract:
The present invention addresses the problem of providing a polarizing plate protective film that contains a hydrogenated norbornene resin, does not increase haze, and has improved slip properties. The present invention also addresses the problem of providing a production method for the polarizing plate protective film and a polarizing plate that comprises the polarizing plate protective film. The polarizing plate protective film contains a hydrogenated norbornene resin and fine particles and is characterized in that the average particle size of secondary particles of the fine particles is 0.05-0.20 µm, in that the relative standard deviation of the average particle size of the secondary particles is 5%-20%, and in that the peak density of the surface of the polarizing plate protective film is 1000-5000 (parts/mm2).
