Abstract
Bistable and analog FLC devices employing chiral nonracemic liquid crystal materials exhibiting de Vries smectic A phases. The invention provides certain liquid crystal material that can be employed in both bistable and analog device configurations. The invention also provides a method for identifying liquid crystal materials that will exhibit both bookshelf structure in SSFLC cells and provide V-shaped switching in an analog device configuration.
