    Abstract: A liquid crystal display (LCD) includes an upper board and a lower board that couple each other and form a space therebetween, a liquid crystal layer sandwiched between the upper board and the lower board and a plurality of spacers located in the space between the upper board and the lower board. The spacers are conductive so that the liquid crystal layer and the spacers form two equivalent parallel resistive paths to conduct the extra charges in the liquid crystals. When the LCD is subject to an external high static charge source, the static partial voltage found in the liquid crystal layer is reduced because of the lower equivalent parallel resistance, thus the damage and the interference on the liquid crystals in the liquid crystal layer caused by the external static charge source may be reduced.
