Abstract
In a liquid crystal display, a liquid crystal is in the form of a layered structure between first and second substrates which are spaced apart from and parallel to each other. An intrinsic electric field is applied between the first and second substrates for controlling orientation of liquid crystal molecules, and that at least two electrodes are formed on any of the first and second substrates spaced apart from each other and applied with different voltages so that at least a lateral electric field is generated in parallel to surfaces of the first and second substrates. Planes of the layered structure of the liquid crystal are just or almost vertical to a direction of the lateral electric field.
