ABSTRACT:
A pixel electrode or a common electrode is a light-transmissive conductive film; therefore, it is formed of ITO conventionally. Accordingly, the number of manufacturing steps and masks, and manufacturing cost have been increased. An object of the present invention is to provide a semiconductor device, a liquid crystal display device, and an electronic appliance each having a wide viewing angle, less numbers of manufacturing steps and masks, and low manufacturing cost compared with a conventional device. A semiconductor layer of a transistor, a pixel electrode, and a common electrode of a liquid crystal element are formed in the same step.
