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.
