First Claim
Patent Images
1. An electrode structure of a wide viewing angle liquid crystal display comprising:
- a scan signal line;
a data signal line perpendicular to said scan signal line, said scan signal line and said data signal line defining a pixel area;
a common electrode in said pixel area;
a passivation layer above said common electrode; and
a plurality of pixel electrodes each having a herringbone-shaped structure and running substantially in parallel with said data signal line above said passiviation layer and said common electrode;
wherein said common electrode has a plate-shaped structure substantially filling said pixel area below said plurality of pixel electrodes.

Abstract
An electrode structure for a liquid crystal display includes a layer of pixel electrodes each having a herringbone-shaped structure, a passivation layer and a layer of common electrodes. The pixel electrodes are formed in parallel above the common electrodes. The herringbone-shaped structure of a pixel electrode has a predefined turning angle between 45 degrees to 90 degrees. The pixel electrode structure allows the liquid crystals in the display to rotate in two directions, clockwise and counterclockwise, to compensate for the color dispersion caused by a wide viewing angle.
