Abstract

PURPOSE: A chemically stable nematic crystal composition enabling white and clear displaying consists of either sole compostition of two or more of trans (equatorial- equatorial) 1,4-di-substituted-cyclohexane derivatives or a composition of such derivatives added with other nematic or non-nematic liquid crystal compounds in a proper amount.
CONSTITUTION: Two or more of trans 1,4-substitutted-cyclohexane derivatives represented by the formula (R:C3W7 straight chain alkyl group, R':C2W5 straight chain alkoxyl group) are mixed to form a composition. Alternately, one or more of the above derivatives are mixed with a specified proportion with one or more of nematic liquid crystal compounds having a large positive, negative, or small positive dielectric constant anisotropy, represented by the formulas (many described in other places) and/or their homolog non-nematic liquid crystal compounds to form a composition. Such compositions, in which the compound of the formula is very compatible wiht other components, provides chemical stability and long service life and is free of crystal precipitation known to the previous system. This, together with clear and white displaying property, is very suited as FEM cell.
