Abstract:
An active cell for a thin-film transistor liquid crystal display on a substrate, said active cell comprising:a switching device on said substrate; a data line for supplying data signals to said switching device; a scanning line for supplying controlling signals to said switching device; a planarization layer on said switching device and said substrate, said planarization layer having a contact opening which is extended down to a driven end of said switching device; a light shielding layer on a portion of said planarization layer; a dielectric layer on said light shielding layer and a top planar region of said planarization layer; a first electrode layer on said dielectric layer and said planarization layer, said first electrode communicating to said driven end of said switching device through said contact opening; a liquid crystal layer on said substrate; a second electrode layer on said liquid crystal layer; and a counter plate on said second electrode layer.
