Polarizing plate and optical display device comprising same

A polarizing plate comprising:

• a polarizer;
• a protective film stacked on an upper surface of the polarizer;
• and
• a retardation film stacked on a lower surface of the polarizer,
• wherein the retardation film includes a first retardation layer and a second retardation layer that is a coating layer disposed on one surface of the first retardation layer,
• the protective film has a total haze of 19% or more and an internal haze of 7% or more, at a wavelength of 550 nm to 555 nm, and
• the polarizer has a polarization degree of 99.5% or more;
• wherein the polarizing plate satisfies at least one of the following:
• the second retardation layer has a slow axis of +79° to +89° or −89° to −79° with respect to a MD of the first retardation layer;
• and
• the first retardation layer has an in-plane retardation of 200 nm to 270 nm at a wavelength of 550 nm, and the second retardation layer has an in-plane retardation of 80 nm to 140 nm at a wavelength of 550 nm.
