Polarizing plate and optical display device comprising same

Abstract

Provided are a polarizing plate and an optical display device comprising same, the polarizing plate comprising: a polarizer; and a first phase difference layer, a second phase difference layer and a third phase difference layer which are sequentially stacked on the lower surface of the polarizer. The first phase difference layer comprises a positive C phase difference layer. The second phase difference layer has positive wavelength dispersibility and an in-plane phase difference of approximately 200 nm to 280 nm in a wavelength of 550 nm. The third phase difference layer has positive wavelength dispersibility and an in-plane phase difference of approximately 80 nm to 145 nm in a wavelength of 550 nm. When the absorption axis of the polarizer is 0°, the angle formed by the slow axis of the second phase difference layer is approximately +14° to +24° or approximately −24° to −14°, and the angle formed by the slow axis of the third phase difference layer is approximately +79° to +89° or approximately −89° to −79°.
