Abstract
A multi-domain wide viewing angle liquid crystal display (LCD) has a plurality of bump-with-slit structures formed on at least one substrate. Each bump-with-slit structure in a single pixel area includes a plurality of slits formed on the electrodes and a plurality of bumps formed above the slits. It uses the combination of bumps and electrode slits to control the directions of the pre-tilted angles of liquid crystal molecules and to form multiple domains. The capacity storage area is designed and located under the slit of the electrode. Such capacity storage area has the function of covering the disclination lines. The LCD structure decreases the color dispersion of the LCD, increases the response speed and reduces the generation of disclination lines. Moreover, the driving voltage for the LCD is lower and the process window is larger. Because the generation of disclination lines is reduced, the aperture ratio under the black matrix area of the multi-domain wide-viewing angle LCD of the invention is increased by 15% to 20% as compared to the conventional multi-domain LCD.
