Abstract
The object of the present invention is to improve the conventional manufacturing method for reducing the manufacturing steps, which has small tolerance error and low yield rate. To achieve the object, novel technique is employed to rationalize the step of islanding a semiconductor layer and the step of forming an etching stop layer by applying halftone exposure technique. Novel technique is employed to rationalize the step of forming a protection layer on the electrode terminal by applying halftone technique in the anode oxidization step for source/drain wiring in the conventional skill. Four-mask process and three-mask process schemes are employed to produce TN-type liquid crystal display device and IPS-type liquid crystal display device by technically combining the rationalized techniques of simultaneously forming pixel electrodes and scan lines of conventional skill.
