Abstract

The cholesteric liquid crystal material may be used in electro-optical devices for light modulation, and, in particular, for the reproduction of digits, signs and images. It has high electro-optical properties. It attains a high contract and high speed of relaxation, both in the application of an electrical field and upon its switching off. The relaxation times during cholesteric-nematic transitions are from 5 to 10 times smaller than those of the conventional cells. By varying the proportion of the components, optimal characteristics may be attained.The material is based on a mixture of nematic liquid crystal, selected from the group n-ciano-n'-alkyl-phenyl-cyclohexane, which additionally contains n-decyloxibenziliden-n'-amino-2-methylbutylcinamate (in quantities between 5 and 25 % weight p.), added to the nematic.
