Abstract

We investigated the relationships between the viewing-angle optical properties and the device parameters in an OCB-LCD compensated with hybrid aligned discotic liquid-crystal films and C-plates. We verified that the polar angle dependence of the sum of the retardation of the LC layer in the dark state and the compensation films, Rettotal, of the rubbing direction is a useful guideline for optimizing the design parameters, and that a wide viewing angle could be achieved in all azimuth angles by optimizing all design parameters of the compensation films, including the hybrid angle and pretilt angle of the discotic liquid-crystal films.
