Abstract:
A wide viewing angle compensation polarizing plate of the invention comprises a laminate comprising an optical film (1) that is formed of an obliquely oriented material exhibiting optically-negative uniaxiality, an anisotropic light-scattering film (2) and a polarizer (3). The wide viewing angle compensation polarizing plate can widen viewing angle characteristics both in the lateral and vertical directions with respect to the direction of the normal to the screen when used in liquid crystal displays.
