V-Shaped Switching in Thresholdless Antiferroelectric Liquid Crystals : Probable Interface-Induced Type and Possible Intrinsic Type

Abstract

The thresholdless, hysteresis-free, V-shaped switching in an apparently antiferroelectric lqiuid crystal mixture is very promising in realizing attractive liquid crystal displays. [Proc. Asia Display'95 (Hamamatsu) 61]. In this report we will show an example of interface-induced thresholdless antiferroelectricity ; the substrate interfaces induce tilting randomization and Langevin type alignment from layer to layer, which are considered to be fundamental to the V-shaped switchng.
