A Transflective Liquid Crystal Device and Method of Manufacturing the Same适用于显示器的多晶硅薄膜象素电极

总结

The present invention presents the construction of electrodes for liquid-crystal cells using metal-induced laterally crystallized (MILC) polycrystalline silicon (Poly-Si), and the integration of these electrodes in the construction of thin-film transistors. MILC poly-Si. This is shown to possess adequately high electrical conductance and low absorption of visible light. Integration is possible since the MILC poly-Si is also known to be a good material for the construction of thin-film transistors. Furthermore, the same dielectric material can be used both as the gate dielectric for transistors and insulators covering the electrodes.

Replacement of conventional indium-tin oxide by MILC poly-Si leads to process simplification, with the elimination of (1) deposition and patterning of and (2) formation of contact holes to the indium-tin oxide electrode. Ultimately, such replacement results in significant reduction of manufacturing costs.
