Abstract
A closed-cavity liquid-crystal display is provided, which is a liquid-crystal display having a wide angle of view. The liquid-crystal display comprises: an insulator layer formed with a plurality of cavities extending completely through the insulating layer, in which liquid-crystal material is filled into the plurality of cavities; a first substrate, placed on one side of the insulator layer, in which a first electrode is formed on one side of the first substrate near the insulator layer; and a second substrate, placed on the other side of the insulator layer, in which a second electrode is formed on one side of the second substrate near the insulator layer, so that the first electrode and the second electrode are used to drive and vary the alignment of liquid-crystal molecules in the plurality of cavities. The inner circumference of the closed cavity is coated with a homeotropic alignment agent, so that the alignment of the liquid-crystal molecules is circularly symmetric, and the optical performance of the liquid-crystal display is independent of the azimuthal angle.
