1. A pixel structure of a thin film transistor liquid crystal display, comprising:
a substrate;
a first metal conductive layer, disposed on a surface of the substrate;
a first insulating layer, disposed on surfaces of the first metal conductive layer and the substrate;
a semiconductor layer, disposed on a surface of the first insulating layer;
a second metal conductive layer, disposed on surfaces of the first insulating layer and the semiconductor layer;
a second insulating layer, disposed on a surface of the second metal conductive layer;
a third metal conductive layer, disposed on a surface of an organic insulating layer and forming a common electrode;
a passivation layer, disposed on surfaces of the organic insulating layer and the third metal conductive layer;
a transparent conductive layer, disposed on a surface of the passivation layer and electrically insulated from the third metal conductive layer;
wherein the passivation layer included between the third metal conductive layer and the transparent conductive layer acts as a storage capacitor required for the pixel.
