Title: Method of manufacturing array substrate for liquid crystal display device
Inventor: HWANG KWANG-JO
IPC: H01L29/786
Filed: 2002-03-28
Abstract: PROBLEM TO BE SOLVED: To improve the numerical aperture of a liquid crystal display device by using two or more minute slits much narrower than a single slit to reduce the distance between pixel electrodes constituted on an array substrate for liquid crystal display device and forming a minute pattern of data wiring. SOLUTION: An exposed transparent electrode layer is so etched after exposure of an exposed photo-resist that a minute area on which light is made incident through a diffraction slit corresponds to an area between preliminarily defined pixel electrodes, and thus pixel electrodes constituted with a minimum gap kept are formed. Since the gap between the pixel electrodes is minimized by this method, the width of data wiring constituted between pixel electrodes can be made narrower. Consequently, the liquid crystal display device which has the numerical aperture improved is manufactured.
