Abstract
A polarizing plate and an optical display apparatus are disclosed. A polarizing plate includes a polarizer and a protective film stacked on a light exit surface of the polarizer, and the protective film includes a polyester based base layer and an antiglare layer stacked on a surface of the polyester based base layer, and the protective film has an in-plane retardation of 100 nm to 4,000 nm at a wavelength of 550 nm, a total haze of 40% to 80%, and a ratio of internal haze to external haze of greater than 0 to 0.2.
