PA34 Three-dimensional kinks of c-director in a ferroelectric liauid crystal

Abstract

We studied about orientation of c-director in freely suspended ferroelectric liquid crystal films. In a polarizing microscopic observation, any texture has been observed. It does not support a result of 4×4 matrix simulation on an assumption that all molecules orient uniformly in each layer, and suggests that molecular orientation has kinks in each smectic layer. These kinks do not make any disclination or dislocation and accompany a helical structure.
