Liquid crystal display and method for driving the same.

摘要

A liquid crystal display includes a liquid crystal cell including a pair of substrates (1,2) opposite to each other, each substrate having an electrode film and an orientation control layer (9, 19) thereon, and a ferroelectric liquid crystal filled between the substrates; and a pair of polarizing plates which are provided opposite to each other in the state of "cross nicol" on both sides of the liquid crystal cell (18); the ferroelectric liquid crystal being bistable in the liquid crystal cell (18), the polarizing plates being oriented in such a manner that one of their polarizing directions conforms to one of extinction positions of the ferroelectric liquid crystal under no electric field, the liquid crystal cell being applied with an alternating voltage for changing an apparent tilt angle of the ferroelectric liquid crystal depending on the applied voltage value, resulting in display with gray scale. <IMAGE> <IMAGE>
