Claim:
1. A polarizing plate comprising: a polarizer; a first retardation film on a lower surface of the polarizer and having an in-plane retardation (Ro) at a wavelength of about 550 nm of about 180 nm to about 220 nm; and a second retardation film on a lower surface of the first retardation film and having an in-plane retardation (Ro) at a wavelength of about 550 nm of about 50 nm to about 80 nm, wherein the first retardation film has a thickness direction retardation (Rth) at a wavelength of about 550 nm having a positive (+) value, and the second retardation film has a thickness direction retardation (Rth) at a wavelength of about 550 nm having a negative (−) value.
