TFT active matrix liquid crystal display devices with two layer gate lines, the first being the same level and material as gate electrodes

A liquid crystal display device having a plurality of pixels, each of said plurality of pixels including a thin film transistor, a pixel electrode and a holding capacitance element and disposed in each of intersecting regions defined by two adjacent scanning signal lines and by two adjacent image signal lines, wherein:

• each said thin film transistor comprises a gate electrode electrically connected to one of said two adjacent scanning signal lines associated therewith, a gate insulating film disposed on said gate electrode, a semiconductor layer disposed on said gate insulating film, and a source electrode and a drain electrode electrically connected to said semiconductor layer, respectively,
• one of said source electrode and drain electrode of each said thin film transistor is electrically connected to said pixel electrode associated therewith, the other of said source electrode and drain electrode of each said thin film transistor being electrically connected to one of said two adjacent image signal lines associated therewith,
• said scanning signal lines include a first conductive film and a second conductive film superposing with each other,
• said holding capacitance element of each pixel comprises a first electrode electrically connected to said pixel electrode, a second electrode electrically connected to the other of said two adjacent scanning signal lines associated therewith, and a dielectric film interposed therebetween, and
• said second electrode and said gate electrode are formed from a same conductive layer only, which conductive layer is a same level layer as that of said first conductive film of said scanning signal lines.
