Fabrication of Half-V-FLCDs Using Photoalignment and Their Display Performances

Abstract

Ferroelectric liquid crystal materials without having SA phase in their phase sequence show Half-V switching. We have adopted photoalignment to fabricate H-V-FLCD using this kind of FLC material and the results were compared with those by using rubbing technique. It is shown that EO characteristics of H-V-FLCD is strongly dependent on the surface anchoring, and actually photoalignment produces low voltage operation and large deflection apparent tilt angle of FLC molecules.
