Dependence of threshold behavior upon surface distribution of polymer chains in a twisted nematic liquid crystal.

Abstract

On the basis of a general Rapini and Papoular equation and a unified surface anchoring energy theory, dependence of the threshold behavior of the liquid crystal director upon the statistical distribution of polyimide chains is theoretically investigated for a twisted nematic liquid crystal cell. We assumed that the anisotropy distribution of polyimide… (More)
