POLARIZING PLATE AND OPTICAL DISPLAY INCLUDING THE SAME |
| 摘要 |
A polarizing plate includes a polarizer; a first retardation film formed on a lower surface of the polarizer and having an in-plane retardation (Ro) at a wavelength of about 550 nm of about 180 nm to about 220 nm; and a second retardation film formed on a lower surface of the first retardation film and having an in-plane retardation (Ro) at a wavelength of about 550 nm of about 50 nm to about 80 nm. The first and second retardation films have thickness direction retardations (Rth) of opposite signs at a wavelength of about 550 nm. An optical display includes the polarizing plate. |

1. A polarizing plate comprising:
a polarizer; a first retardation film on a lower surface of the polarizer and having an in-plane retardation (Ro) at a wavelength of about 550 nm of about 180 nm to about 220 nm; and a second retardation film on a lower surface of the first retardation film and having an in-plane retardation (Ro) at a wavelength of about 550 nm of about 50 nm to about 80 nm, wherein the first and second retardation films have thickness direction retardations (Rth) of opposite signs at a wavelength of about 550 nm. |
