1. A polarizing plate comprising:
a polarizer; and
a first retardation layer and a second retardation layer sequentially stacked on a lower surface of the polarizer,
wherein the first retardation layer has a short wavelength dispersion of about 1 to about 1.03, a long wavelength dispersion of about 0.98 to about 1, and an in-plane retardation of about 180 nm to about 220 nm at a wavelength of 550 nm,
the second retardation layer has a short wavelength dispersion of about 1 to about 1.1, a long wavelength dispersion of about 0.96 to about 1, and an in-plane retardation of about 70 nm to about 120 nm at a wavelength of 550 nm, and
a ratio (Rth/d) of out-of-plane retardation (Rth) (unit: nm) of the second retardation layer at a wavelength of 550 nm to thickness (d) (unit: μm) of the second retardation layer is from about −33 nm/μm to about −15 nm/μm, and
wherein the second retardation layer is directly formed on the first retardation layer.
