摘要： An optical film and a polarizing plate including the same are provided. The optical film includes an acrylic resin having a glass transition temperature of 120° C. or higher and including an alkyl (meth)acrylate-based repeating unit and a styrene-based repeating unit, and a UV absorbent having a 1% thermal decomposition temperature greater than or equal to a temperature 2.5 times that of the glass transition temperature of the acrylic resin.
