Abstract:
1. A liquid crystal display device comprising: a common electrode; a wiring over and electrically connected to the common electrode; a first insulating film over the common electrode and the wiring; a pixel electrode over the first insulating film; a liquid crystal over the common electrode and the pixel electrode; a transistor electrically connected to the pixel electrode; a gate wiring electrically connected to the transistor; and a source wiring electrically connected to the transistor, wherein the common electrode overlaps the gate wiring, the wiring, a semiconductor film of the transistor, the source wiring, and the pixel electrode, wherein the wiring comprises a copper film or a stacked structure in which an aluminum film is sandwiched between molybdenum films, wherein the pixel electrode comprise a plurality of openings, wherein the first insulating film is provided over the transistor, wherein each of the common electrode and the pixel electrode is a light-transmitting conductive film, and wherein an orientation of the liquid crystal is configured to be controlled by an electric field between the common electrode and the pixel electrode.
