Ferroelectric liquid crystal composition and liquid crystal display device

摘要

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) at least one compound expressed by the following general formula (2), and at least one compound expressed by the following general formula (3) wherein R1 to R6, ring A-B, A, X1, and X2 are herein defined.
