摘要：
A compound represented by formula (I): ##STR1## wherein R represents a straight chain alkyl group having from 1 to 9 carbon atoms; ##STR2## represents ##STR3## represents a hydrogen atom or a fluorine atom; and ##STR4## has a trans (equatorial-equatorial) configuration, is disclosed. The compound of formula (I) exhibits a nematic phase in the vicinity of room temperature or in a temperature range higher than room temperature and has a small optical anisotropy and a positive dielectric anisotropy and is, therefore, useful in preparing a liquid crystal display cell excellent in viewing-angle characteristics.
