Method for fabricating thin film transistor array substrate for liquid crystal display
The present invention discloses a TFT array substrate (and method for making the same) having the large storage capacitance for use in a liquid crystal display device. In a four-mask process, the conventional storage capacitor of the TFT array substrate includes the capacitor electrodes and the insulation layer and semiconductor layer as a dielectric layer. However, the present invention includes the capacitor electrodes and the insulation layer as a dielectric layer so that the thickness of the dielectric layer becomes thinner. Therefore, much more electric charges can be stored in the storage capacitor. That means the liquid crystal display device can have a high picture quality and a high definition. Moreover, the present invention has a structure that can achieve the high manufacturing yield.
