Abstract

A method of fabricating a pixel structure is provided. First and second gate lines, first and second gates and a connecting line are formed on the substrate, wherein the first and second gates are disposed at two sides of the connecting line and between the first and second gate lines. A gate insulating layer is formed. First and second semiconductor layers are respectively formed on the gate insulating layer above the first and second gates. First and second source/drain regions are formed respectively on the opposite sides of the first and second semiconductor layers, and drain lines are formed on substrate. An insulating layer having an opening is formed on the substrate, and the opening is disposed above and exposes the connecting line. A common electrode is formed on the insulating layer and electrically connects to the connecting line through the opening. First and second pixel electrodes are formed on the common electrode and electrically connect to the first and second drain regions respectively.

Description

technical field [0001] The present invention relates to an element and its manufacturing method, and in particular to a pixel structure and its manufacturing method. Background technique [0002] In recent years, with the maturity of optoelectronic technology and semiconductor manufacturing technology, the flat panel display (FlatPanelDisplay) has been vigorously developed. Liquid crystal displays have the advantages of low-voltage operation, no radiation scattering, light weight, and small size. Therefore, they gradually replace traditional cathode ray tube displays and become the mainstream of display products in recent years. However, liquid crystal displays still have the problem of limited viewing angles. At present, the technologies that can meet the requirement of wide viewing angle include twisted nematic (twistednematic, TN) liquid crystal plus wide viewing film (wideviewing film), in-plane switching (IPS) liquid crystal display, fringe field switching (FringeField...
