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.

Polymeric orientating material and ferroelectric liquid crystal display

A liquid crystal display device includes a pair of substrates, a pair of transparent electrodes formed on the substrates, a pair of orientation layers consisting of at least two coating layers formed on the transparent electrode and a liquid crystal material layer, to thereby reduce a defect rate due to rubbing. Since two or more orientation materials having different pre-tilt angles are used, control of the pre-tilt angle is advantageous so that a disinclination defect generated when voltage is applied can be removed. The liquid crystal orientation is stable and uniform.
