Abstract:
A pixel structure of a thin-film transistor liquid crystal display, suitable to be formed on a transparent substrate, the pixel structure comprising:a pixel, formed on the transparent substrate, the pixel having a low-temperature polysilicon thin-film transistor and a pixel electrode, wherein the low-temperature polysilicon thin-film transistor comprises a gate and a source/drain region having one side electrically connected to the pixel electrode; a scan line, formed on the transparent substrate and electrically connected to the gate; a signal line, formed on the transparent substrate and electrically to the other side of the source/drain region; and a storage capacitor, formed underneath the signal line, the storage capacitor having a doped polysilicon layer, a dielectric layer and a shielding metal layer, wherein the shielding metal layer is formed on the doped polysilicon layer and is electrically connected to the pixel electrode.
