Abstract

We extend our preliminary investigation of the conic cylindrical-cavities liquid crystal display using vertical aligned liquid crystal structures to obtain a wide viewing- angle. We simulate the director distribution of CCLCD as well as the optical propagation to study the optical transmission and the viewing angle. The simulation of director distribution is based on the tensor form formulation of the free energy density. The differential equations satisfied by the steady-state director distribution are derived from this form of free energy and are solved in conjunction with the Poisson equation. The simulation of optical propagation and the calculation of the optical transmission coefficient are based on the extended Jones matrix method. We first show by simulation that indeed CCLCD can have a wide-viewing angle and gray levels but no gray-scale inversion. The validness of our simulation is also proved by performing some test experiments.
