ABSTRACT:
A nematic liquid crystal composition composed of (i) at least one compound of the general formula ##STR1## wherein R.sub.1 represents n-C.sub.m H.sub.2m+1, R.sub.2 represents n-C.sub.q H.sub.2q+1 -O, and m and q are integers of 1 to 10,
(ii) at least one compound selected from the group consisting of nematic liquid crystalline compounds having positive dielectric anisotropy and homologs thereof, and (iii) as an optional ingredient, at least one compound selected from the group consisting of nematic liquid crystalline compounds having negative dielectric anisotropy and homologs thereof. This liquid crystal composition is colorless and chemically stable and has superior multiplexing drive characteristics. These properties render it useful as a display element.
