Abstract: A liquid crystal display device having a pixel electrode, a counter electrode, and a liquid crystal between the electrodes. Liquid crystal molecules in contact or near the respective opposed surfaces of the electrodes have specified pretilt angles as a result of the conditioning of those surfaces. When no voltage is applied, the liquid crystal is in a splay alignment state; applying voltage prior to image display causes a transition of transformation of the splay alignment state to a bend alignment state; image display is carried out under the bend alignment state. Transition from the splay alignment state to the bend alignment state is promoted by having a large pretilt angle domain formed on at least one of the electrode surfaces causing a larger pretilt angle of liquid crystal molecules than is present in a region surrounding the large pretilt angle domain.

Abstract: In a liquid crystal display device which displays images by changing light transmission through formation of a bend alignment state of the liquid crystal, a large pretilt angle domain is formed on at least either the surface of the pixel electrode or the surface of the counter electrode and the large pretilt angle domain is so conditioned as to cause a larger pretilt angle of the liquid crystal molecules than the surrounding region does. This permits quick, reliable transition from a splay alignment state to the bend alignment state. Such transition is also facilitated by adding a chiral agent to a liquid crystal. A combination of the large pretilt angle domain and a chiral agent further facilitates occurrence of the transition.
