  • Patent number: 6501522
    Abstract: A method of fabricating a reflective type LCD, having the steps of: (a)providing a substrate; (b) forming a polymer resin layer on the substrate; (c) forming a positive-type photoresist layer on the polymer resin layer, wherein the upper surface of the photoresist layer has a convex/concave profile; and (d)performing a dry etching process to completely remove the photoresist layer and partially remove the polymer resin layer so as to shape the upper surface of the polymer resin layer into a convex/concave profile.
    Type: Grant
