ABSTRACT:
A liquid crystal display without storage capacitance electrode lines. At least one storage capacitor structure including first and second metal layers and a dielectric layer disposed therebetween is formed on a lower substrate. The first and second metal layers are discrete. The second metal layer is electrically connected to the pixel electrode and is located above the first metal layer. The second metal layer overlaps a portion of the first metal layer. An insulating spacer is formed on the interior of an upper substrate and extended into a liquid crystal layer to maintain a cell gap. A common electrode is conformally formed on the upper substrate and the insulating spacer to electrically connect the first metal layer via a discrete transparent conductive layer.
