Claim 0:
1. A polarizing plate comprising:
a polarizer; and a first protective layer and a second protective layer sequentially stacked on a surface of the polarizer,
wherein the second protective layer comprises a positive C retardation layer,
the positive C retardation layer having a thickness of about 10 μm or less, an index of refraction of about 1.50 to about 1.55, and a glass transition temperature (Tg) of about 150° C. to about 250° C., and
wherein a difference in index of refraction between the positive C retardation layer and the polarizer is about 0.05 or less, and
an index of refraction of the first protective layer is the same or less than that of the positive C retardation layer.
