Abstract

A method for producing a substrate of a reflection type liquid crystal display device is provided. The method includes the steps of: forming the input portion for inputting a signal from outside and the connecting electrode on the substrate on which the reflective electrode is formed; forming a protective film on the connecting electrode; forming an interlayer insulator under the condition that the protective film on the connecting electrode is exposed; patterning the interlayer insulator; forming a reflective electrode film on the interlayer insulator; patterning the reflective electrode film to form the reflective electrode; and removing the protective film on the connecting electrode to expose the connecting electrode.
