ABSTRACT:
An improved liquid crystal composition for use in a liquid crystal light valve is provided. The light valve includes a liquid crystal panel having two opposed transparent substrates with transparent electrodes disposed on the inner surfaces thereof with the liquid crystal material disposed between the substrates. The liquid crystal panel controls light transmittance in response to signals of higher frequency h.sub.f and lower frequency h.sub.l than a crossing frequency f.sub.c (wherein the dielectric anisotropy is zero) applied to the liquid crystal material, respectively or simultaneously. The improved liquid crystal composition includes the following compounds in the weight percent concentrations as indicated:
