A liquid crystal display device has a wiring electrode and an independent gap electrode without wiring formed on a substrate, and an insulating film formed on the wiring and gap electrodes. A first display electrode, an outer second display electrode, and an inner second display electrode are formed on the insulating film and are electrically connected to the wiring electrode or the gap electrode via respective contact regions provided in the insulating film. The first display electrode overlaps with an edge portion of the gap electrode through intermediation of the insulating film. The outer second display electrode and the inner second display electrode each overlap with another edge portion of the gap electrode through intermediation of the insulating film. By such a construction, the wiring electrode is prevented from being visible or from having portions thereof being half-lit.
