A multi-domain liquid crystal display (LCD) has a plurality of wall-bump structures formed on a common electrode layer on a substrate. Each wall-bump structure consists of at least one wall-bump disposed in a pixel area. Wall-bumps of many different shapes can be used in the wall-bump structure. The wall-bump structure is manufactured by a standard photo-lithographic process. It provides pre-tilted angles for liquid crystal molecules and results in orderly alignment of liquid crystal molecules when an external voltage is applied. By means of the fringe field effect to tilt liquid crystal molecules, a multi-domain LCD cell can be established after a voltage is applied. The multi-domain LCD provides fast response speed for its application and higher transmittance than a conventional vertically aligned wide-viewing angle LCD.
