摘要：
Ferroelectric liquid crystal compositions containing the following components (A), (B) and (C). Component (A): at least one compound represented by the general formula (A):
Component (B): at least one compound represented by the general formula (B):
Component (C): at least one compound selected from the compounds represented by the general formula (C-a):
and the compounds represented by the general formula (C-b):
All the symbols are as defined in the appended claims. The compositions exhibit quick response and have the SC * phase over a wide temperature range, and thus are suitable for use in light switching devices.
