Abstract:
1. A liquid crystal display device comprising: a switching element that has a drain electrode and that is arranged on a substrate; a first insulating film that covers the switching element and that has a first opening on the drain electrode; a first etching stopper electrode that is formed in the first opening and that is connected to the drain electrode; a common electrode that is arranged on the first insulating film; a second insulating film that covers the first etching stopper electrode and the common electrode, and that has a second opening on the first etching stopper electrode, wherein the second insulating film is formed in a space between the common electrode and the first etching stopper electrode; and a pixel electrode that is connected through the second opening to the first etching stopper electrode and that extends onto the second insulating film so as to face the common electrode and overlap both of the first etching stopper electrode and the common electrode.
