Abstract
A wide viewing angle liquid crystal display and method of manufacturing the same. A color filter layer is formed above a substrate having thin film transistors. Pixel electrodes and common electrodes are formed above the color filter layer. Since no thick color filter layer is formed between a liquid crystal layer and the pixel electrodes/common electrodes, driving voltage for the liquid crystal display is lowered and the quantity of trapped electric charges is reduced.
