Abstract
The invention provides a liquid crystal (LC) composition, a LC device such as a liquid crystal display and a phase modulator, and a method thereof. The liquid crystal composition comprises a liquid crystal and a polymer. The liquid crystal exhibits a macroscopic anisotropic property such as optical property in the absence of the polymer under a condition such as certain temperature. The polymer in the composition stabilizes the liquid crystal so that the liquid crystal exhibits a macroscopic isotropic property under the same condition, and the liquid crystal stabilized by the polymer exhibits the macroscopic anisotropic property when an electrical field is applied thereon. The devices exhibit technical merits such as large viewing angle, fast response time, better contrast ratio, easy manufacturability of large size display with improved dark state, easy manufacturing process with wider temperature region, and polarization-insensitivity of PSI phase modulator, among others.
