摘要:
A forming method of the present invention includes forming a first patterned conductive layer, which includes a transparent conductive layer and a metal layer stacked together on a substrate, where the first patterned conductive layer functions as gate lines, gate electrodes, common lines and predetermined transparent pixel electrode structures; and forming a second patterned conductive layer on the substrate. The second patterned conductive layer includes data lines and reflective pixel electrodes, and be directly connected to doping regions, such as source regions/drain regions. According to the forming method of the present invention, pixel structures of a transflective liquid crystal display device can be formed through five mask processes. Therefore, the manufacturing process of the transflective liquid crystal display device is effectively simplified, so the product yield is improved and the cost can be reduced.
