The alignment distribution in memory states of liquid crystals by applying an in-plane field

Abstract

Liquid crystal alignment and memory properties on a polymer surface after applying and removing the voltage are studied. Two dimensional Stokes parameters of the memorized region are obtained and twist angle distributions are measured by using the Stokes parameter method (SPM). The result implies that the twist angle of LC molecules in the memory region decreases continuously as increasing the distance from the electrode edge. The maximum twist angle was smaller than 90°.
