Abstract
A liquid crystal display device includes a substrate having one or more electrodes formed onto one major surface thereof. The substrate and electrodes are then coated with a layer of a dielectric material through which is formed a plurality of openings or vias. Into the openings is disposed a layer of a light influencing material, such as a color filter medium, a liquid crystal material, or an alignment material. In the embodiment in which the light influencing material is a liquid crystal material, it is possible to put one or more different liquid crystal materials into each opening. This allows two adjacent openings to project light of a substantially different character, based on the differing material disposed in each opening.
A method for forming a liquid crystal device such as that described above includes the step of providing a liquid crystal display substrate, and forming at least one, and preferably a plurality of electrodes on a surface thereof. Thereafter, a layer of dielectric material is formed onto the surface of the electrodes and substrate. The dielectric material is the treated, as by a laser, to form a plurality of holes or openings therein. Into the openings is disposed the light influencing material.
