Abstract

Alkyl substituted cyanobicyclohexyl compound mixtures are suitable for use in laser liquid crystal display systems. These materials do not absorb light above 200 nm and are sufficiently stable so that the need for optical filtering is eliminated. Examples of such a mixture include a 1:3 ratio of butyl to ethyl substituted cyanobicyclohexyl compounds. This mixture melts below room temperature to a smectic phase, and becomes nematic at about 47 degrees C and isotropic at 52 degrees C.
