发明名称 Method of making a reflection type liquid crystal display device
摘要 A reflection type liquid crystal display device having excellent display capability even if the number of the photolithography process is reduced and a process for producing the device. A process includes the steps of (a) forming a source/drain wiring by using a first mask; (b) forming a thin film transistor region and gate wiring by using a second mask; (c) forming an opening for a transistor, in a passivation film by using a third mask; (d) forming a rough surface of the interlayer insulating film and to form an opening for the transistor by using a fourth mask by halftone exposure, and (e) forming a reflective metal which extend through the respective openings for the transistor in the passivation film and the interlayer insulating film so that it is electrically connected to the source wiring by using a fifth mask.
