Abstract
A method for manufacturing the pixel structure of a liquid crystal display is provided. In comparison to using seven masks in the conventional lithographic processes for the pixel structure, only four masks are required in the manufacturing method of the present invention. Therefore, the cost of manufacturing is reduced. Furthermore, the unnecessary multilayer structures on the display area can be removed in the manufacturing processes, and thus, enhance the transmittance thereof.
