  • Patent number: 8288212
    Abstract: A method of fabricating a pixel structure of a thin film transistor liquid crystal display is provided. A transparent conductive layer and a first metallic layer are sequentially formed over a substrate. The first metallic 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 sequentially formed over the substrate. A patterning process is performed to remove the first metallic layer in the pixel electrode pattern while remaining the gate insulating layer and the semiconductor layer over the gate pattern. A second metallic layer is formed over the substrate. The second metallic layer is patterned to form a source/drain pattern over the semiconductor layer. A passivation layer is formed over the substrate and then the passivation layer is patterned to expose the transparent conductive layer in the pixel electrode pattern.
