Abstract
The response speed of liquid crystal is enhanced by reducing a distance d between a longer side ( ) of a display electrode and a linear portion ( ) of an orientation control window ( ). On the other hand, a larger orientation control window ( ) (corresponding to a smaller distance d) results in undesirable decrease in contrast of the liquid crystal. Further, the effect of increase in response speed is diminished when the distance d is smaller than the range of 25 &mgr;m to 30 &mgr;m. Therefore, the distance d is preferably in the range of 25 &mgr;m to 30 &mgr;m, and the window ( ) preferably has a width of 7 &mgr;m. An LCD configured to satisfy the above conditions allows improvement in contrast and response speed.
