    Abstract: A multi-domain liquid crystal display (LCD) includes multiple effective pixel electrodes, dummy pixel electrodes and auxiliary electrodes. The effective pixel electrodes are regularly arranged in an array of row and column, and the array of effective pixel electrodes constitute an active display area of the multi-domain LCD. The dummy pixel electrodes are provided outside the active display area and arranged at least on the side of an outermost row or outermost column of the array of effective pixel electrodes. Each auxiliary electrode is positioned next to one side of an effective pixel electrode or a dummy pixel electrode to produce fringe fields and is connected to another effective pixel electrode controlled by a preceding or a succeeding signal line to allow all effective pixel electrodes to have substantially the same coupling capacitance.
