Pretilt angle dependence of the switching behavior in the intrinsic half-V-shaped switching ferroelectric liquid crystal mode

The intrinsic half-V-shaped switching ferroelectric liquid crystal mode (iHV-FLC mode) which is obtained from a material with isotropic (Iso.), cholesteric (Ch) and chiral smectic C (SmC*) phase transition sequences can easily yield excellent moving pictures. There are very few reports of liquid crystal (LC) molecular alignment during the Ch-SmC* phase transition sequence although it is important to clarify the molecular alignment and switching behavior in order to improve device characteristics such as the contrast ratio. We have conducted a detailed observation of the switching behavior of a cell with a striped texture and examined the pretilt angle dependence of the alignment state.
