Abstract
Disclosed is a liquid crystal display device, for controlling liquid crystal by using a latitudinal electric field. Gate wires and drain wires, and switching devices at their intersections, are formed on a transparent active matrix substrate. Source electrodes connected to the switching devices and parallel common electrodes are also formed on the active matrix substrate. Liquid crystal is controlled by an electric field parallel to the surface of the active matrix substrate. By using the same material as are used for color filters, spacers having cylindrical, elliptical, or hemispherical shapes are formed on an opposing substrate at locations that correspond to the intersections of the gate wires and the drain wires.
