Abstract:
The invention relates to a substrate for a liquid crystal display device, a liquid crystal display device provided with the same, and a manufacturing method of the same, and provides a substrate for a liquid crystal display device in which a manufacture process can be cut down and manufacturing cost is reduced, a liquid crystal display device provided with the same, and a manufacturing method of the same. The substrate for the liquid crystal display device includes a pixel electrode formed in each of pixel regions, a plurality of gate bus lines which are formed on a base substrate in parallel with each other and in each of which a plurality of formation materials are laminated and at least a lower layer part is formed of a same formation material as the pixel electrode, a plurality of drain bus lines intersecting with the plurality of gate bus lines through an insulating film and formed to be in parallel with each other, and a thin film transistor formed in each of the pixel regions and including a gate electrode connected to the gate bus line, a drain electrode connected to the drain bus line, and a source electrode connected to the pixel electrode.
