ABSTRACT:
The invention is directed to the use of a liquid crystal composition in a bistable liquid crystal device and especially in a zenithal bistable nematic liquid crystal device, a nematic liquid crystal medium, and a bistable liquid crystal device comprising the liquid crystal composition whereby said liquid crystal composition comprises at least 30 weight % (based on the total weight of the composition) of a component (α) containing one or more compounds having a dielectric anisotropy Δε of at least 25, whereby at least 25 weight % (based on the total weight of the composition) of said compounds have a dielectric anisotropy Δε of at least 40; and at least 5 weight % of a component (β).
