Abstract
A polarizing plate includes a polarizer and a polyester film formed on an upper side of the polarizer. The polyester film has a ratio of MD elongation to TD elongation of about 1:6 to about 1:30. An angle between the transmission axis of the polarizer and the TD of the polyester film ranges from about −7° to about +7°. In some embodiments, a liquid crystal display includes the polarizing plate. The polarizing plate and the liquid crystal display can reduce the occurrence of rainbow spots, realize a high degree of polarization, and exhibit little variation in the retardation and dimensions under high temperature/high humidity conditions.
