Abstract
A wide-viewing angle liquid crystal display having parallel-laid first and second glass panel and a liquid crystal layer in-between. A common line, a transparent insulation layer, a transparent electrode layer and protrusion elements are sequentially laid over the inner surface of the first glass panel, and may include slits. The common line layout incorporates a photomask pattern for forming the protrusion elements during backside exposure. Location and area of the protrusion elements overlaps with a portion of the common line. Furthermore, the protrusion elements and the slits are alternately positioned. In addition, signal bus line and transparent passivation layer can be inserted between the transparent insulation layer and the transparent electrode layer. A portion of the signal bus line and the common line overlap so that area and location of the protrusion elements, a portion of the signal bus line and a portion of the common line overlap.
