Claim:
A method for producing a pixel structure of a thin film transistor liquid crystal display, comprising: (a) preparing a substrate; (b) coating a first metal conductive material on a surface of the substrate to produce a first metal conductive layer, and the first metal conductive layer forms a gate electrode of a thin film transistor structure and a scan signal line of a pixel; (c) coating a first insulating layer and a semiconductor layer onto a surface of the first metal conductive layer; (d) conducting a pattern process for the semiconductor layer, and coating a second metal conductive layer onto a surface of the semiconductor layer, and conducting the pattern process for the second metal conductive layer to produce a drain electrode and a source electrode of the thin film transistor structure; (e) coating at least one second insulating layer onto a surface of the second metal conductive layer by a thin film process, and then coating an organic insulating layer onto a surface of the second insulating layer during the thin film process; (f) coating a third metal conductive layer onto a surface of the organic insulating layer and forming a pattern of a common electrode required by the pixel, and then coating a passivation layer onto a surface of the third metal conductive layer, and forming a contact hole; (g) forming a transparent conductive layer, and producing a pattern of a pixel electrode by the pattern process, and the pixel electrode is electrically connected to the source electrode of the thin film transistor structure through the contact hole, the pixel electrode is insulated from the common electrode, and the passivation layer between the common electrode and the pixel electrode serves as a storage capacitor for the pixel.
