Abstract
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; 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.
