Abstract
A polymeric orientating material for a liquid crystal display including a charged pair electrostatically bound to the main chain of the polymer, and a ferroelectric liquid crystal display adopting the same as an orientation. The ferroelectric liquid crystal display of the present invention has improved memory stability through fast reduction of the anti-electrical field formed when an external electrical field is applied.
