Abstract
A polarizing plate includes a polarizer and a polyester film formed on at least one surface of the polarizer. The polyester film includes a polyester base film and a primer layer formed on at least one surface of the polyester base film. The polyester film contains about 0.1 wt % to about 5 wt % of a UV absorbent. In addition, a liquid crystal display includes the polarizing plate. A method of fabricating a polarizing plate includes preparing a multilayer film containing about 0.1 wt % to about 5 wt % of a UV absorbent, stretching the multilayer film to about 2 to about 10 times its initial length in a transverse direction (TD) to prepare a polyester film, and attaching the polyester film to at least one surface of a polarizer. The multilayer film comprises a polyester base film and a primer layer on at least one surface of the polyester base film.
