Abstract

Provided are a polarizer protection film, a polarizing plate comprising the same, and a liquid crystal display device comprising the polarizing plate. The polarizer protection film has: a moisture permeability ranging from approximately 0 g/m/24 hr to approximately 100 g/m/24 hr; a value for a MD-direction shrinkage rate/a TD-direction shrinkage rate, ranging from 0.8 to 1.3; an in-plane phase difference (Re) ranging from approximately 0 nm to approximately 350 nm; a thickness-direction phase difference (Rth) ranging from approximately 2500 nm to approximately 8000 nm; and a thickness of approximately 10 μm to approximately 60 μm.
