Abstract

An anti-ferroelectric liquid crystal composition consisting essentially of an anti-ferroelectric liquid crystal (A) and a ferrielectric liquid crystal (B) shows a low threshold voltage so that the driving voltage can be decreased, and the composition can give a liquid crystal display device utilizing a fast response time or switching among tristabile states, a distinct threshold voltage characteristic and excellent memory performance.
