Abstract: This invention is directed to a manufacturing method and a new structure of a LCD aligner. The aligner is obtained by using transparency gradually changed mask for lithographic exposure. The LCD aligner made by this method has the function of both multidomain division and that of the retardation film. The advantages of LCD aligners made this way includes: simpler fabrication process, less cost, improved contrast ratio, reduced interference color, etc. Besides enhancing the color resolution of the screen, it also extends the viewing angle of the screen.

Abstract: A color filter is made by depositing a plurality of interference films on a substrate of black matrix material. The films are then selectively etched so that different numbers of films are removed at different locations. The color of the filter at a particular location depends on the number of films remaining at the location after etching.
