the invention provides a liquid crystal 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 .
