ABSTRACT:
A liquid crystal display (LCD) includes a multilayer black matrix system for improving the contrast of displayed images. The black matrix system includes at least one layer of a material that has variable amounts of chemical elements. By, for example, varying "x" and "y" in SiO.sub.x N.sub.y, the refractive index "n" of adjacent SiO.sub.x N.sub.y layers can be slowly varied through the thickness of the system so that the refractive index adjacent the substrate substantially matches that of the substrate and so that there are no overly large refractive index differences between adjacent layers in the system. This reduces light reflections off of the black matrix system.
