Abstract
A polarizing plate, a method of preparing the same and a liquid crystal display apparatus including the same are disclosed. The polarizing plate includes a polarizer and a polyester film formed on a surface of the polarizer, wherein the polyester film has a ratio of an elongation ratio in a machine direction to an elongation ratio in a transverse direction of about 1:0.8 to about 1:1.2, an in-plane retardation (Re) of about 500 nm or less at a wavelength of 550 nm, and an out-of-plane retardation (Rth) of about 10,000 nm or less at a wavelength of 550 nm.
