Ferroelectric chiral smectic liquid crystal composition and light switching element.

摘要

A ferroelectric chiral smectic liquid crystal composition containing two kinds of chiral smectic liquid crystal compound is provided. One of the said compounds shows twist sense of helix of right-handed and the other show twist sense of helix of left-handed and the direction of spontaneous polarization of component chiral smectic liquid crystal compounds is the same. This composition provides a liquid crystal display element which shows very quick response.
