PIXEL STRUCTURE OF THIN-FILM TRANSISTOR LIQUID CRYSTAL DISPLAY

摘要

A pixel structure of a thin-film transistor liquid crystal display. A storage capacitor is formed by simultaneously defining a doped polysilicon layer, a dielectric layer and shielding metal layer and a source/drain region of a low-temperature polysilicon thin-film transistor. The shielding metal layer is formed on the doped polysilicon layer and is electrically connected to a pixel electrode. As the area occupied by the shielding metal layer is the area of the storage capacitor, the aperture ratio is greatly enhanced.
