Polarizing plate, and optical display device including same

Abstract

Provided are a polarizing plate and an optical display device including same, the polarizing plate comprising: a polarizer; and a laminate having a first phase difference layer and a second phase difference layer laminated on the lower surface of the polarizer, wherein the short wavelength dispersion of the first phase difference layer is less than the short wavelength dispersion of the second phase difference layer, the first phase difference layer has, at a wavelength of 550 nm, an in-plane phase difference of 280 nm to 400 nm and a degree of biaxiality of more than 1 and less than 1.6, the second phase difference layer has, at a wavelength of 550 nm, an in-plane phase difference of 140 nm to 260 nm 550 nm and a degree of biaxiality of less than 0, and the difference between the in-plane phase difference of the first phase difference layer and the in-plane phase difference of the second phase difference layer at a wavelength of 550 nm is 130 nm to 150 nm.

Dependencies are inferred from the claim text.
