ABSTRACT:
With respect to at least one of a plurality of TFTs constituting a liquid crystal display device; a signal wiring having one end functioning as a gate electrode of the TFT is formed so as to include: a main portion, formed by patterning a first wiring layer, having a disconnected portion in the vicinity of an active region of the transistor; and a connecting portion, formed by patterning a second wiring layer which is different from the first wiring layer, for interconnecting the disconnected portion. Thus, the breakdown of the gate insulating film of the TFTs during the ion implantation process can be prevented.
