Abstract
Nematic liquid crystal compositions consisting of compounds having high stability with respect to moisture-resistance, oxidation-resistance and light-resistance, complete transparency and a wide range of operating temperatures are disclosed. The compositions are particularly useful for incorporation in a display device in a timepiece, and, more particularly, in a wristwatch. The compounds are mostly of the type wherein two benzene rings are joined by an ester group.
