Abstract
The invention relates to a substrate for a liquid crystal display used in a display section of an information apparatus, a liquid crystal display having the same, and a method of manufacturing the same. There is provided a substrate for a liquid crystal display which achieves good display quality with reduced manufacturing steps, a liquid crystal display having the same, and a method of manufacturing the same. TFTs are formed on a glass substrate. A protective film is formed on the TFTs, and a resist pattern is formed on the protective film, the resist pattern having openings located above source electrodes, gate bus line terminals, and drain bus line terminals. The resist pattern is baked at a baking temperature of 200 (or more after irradiating the surface thereof with ultraviolet light to form a wrinkled resin layer having a wrinkled surface. The protective film and an insulation film are etched using the wrinkled resin layer as an etching mask to form reflective electrodes and protective conductive films on the wrinkled resin layer.
