Surface Polymer Stabilization by Reactive Mesogen in Optically Compensated Splay Mode

Abstract

We have studied the optically compensated splay (OCS) mode applied to polymer stabilization technique using polymerization of reactive mesogen (RM) to reduce or eliminate critical voltage, setting voltage, and phase transition time from bend to splay state. The pretilt angle of almost vertically aligned liquid crystal directors could be lowered through the polymerization of UV-curable RM and applied voltage, at surfaces of vertical alignment layers. To confirm initial stable splay state, we investigated electro-optic characteristics according to concentration of RM in this paper.
