In a semi-transmission type liquid crystal display and a method for fabricating the same, a reflective electrode such as aluminum layer and a transparent electrode such as ITO film are used to form a pixel electrode that is provided on an organic film having an uneven surface. In order to effectively restrict the battery effect between a reflective electrode and a transparent electrode, a surface of the organic film is put in a plasma-processing and then is washed by a washing liquid. Thereafter, the transparent electrode is formed and then the reflective electrode such as a double layer electrode of the aluminum layer and the molybdenum layer are formed.
