ABSTRACT:
A method of fabricating a pixel structure of liquid crystal display is described. A transparent conductive layer and a first metal layer are formed over a substrate sequentially. The first metal layer and the transparent conductive layer are patterned to form a gate pattern and a pixel electrode pattern. A gate insulating layer and a semiconductor layer are formed over the substrate sequentially. A patterning process is performed to preserve the semiconductor layer and the gate insulating layer above the gate pattern and remove the first metal layer of the pixel electrode pattern. A second metal layer is formed over the substrate. The second metal layer is patterned to form a source pattern and a drain pattern. A black material layer is formed over the substrate, and then the black material layer is patterned to form a black matrix pattern uncovering the transparent conductive layer of the pixel electrode pattern.
