Abstract
Ferroelectric liquid crystal compositions having a large dependency of spontaneous polarization on temperature; liquid crystal display devices exhibiting a small dependency of response speed on temperature and making it possible to obtain a wide temperature margin in practical use, and fabricated by using the ferroelectric liquid crystal composition; and methods for driving the devices are provided; the compositions comprising at least one compound expressed by the following general formula (1) ##STR1## at least one compound expressed by the following general formula (2), and ##STR2## at least one compound expressed by the following general formula (3) ##STR3## wherein R.sub.1 to R.sub.6, ring A-B, A, X.sub.1, and X.sub.2 are herein defined.
