Abstract
A use of zwitterionic compound in preparation of dynamic-scattering-mode-based liquid crystal material. A liquid crystal material is also described. Such material contains liquid crystal and dopant, and the dopant is zwitterionic compound. A liquid crystal electro-optical device comprising such liquid crystal compound and the use of such optical device are also described. Zwitterionic compound is used as dopant to induce a stable dynamic scattering mode in liquid crystals.
