Abstract:
1. A display device substrate comprising, on a main surface of a substrate, a structure of alternating layers of: a plurality of interlayer insulating films; and three or more wiring layers, each of the three or more wiring layers being formed from a conductive film, wherein the display device substrate includes a data wiring, and the data wiring is positioned in a third or higher wiring layer from a side of the substrate, wherein the display device substrate includes a plurality of pixel switching transistors that are connected in series, and the plurality of pixel switching transistors overlap with the data wiring when the main surface of the substrate is viewed in plan view, wherein the plurality of pixel switching transistors include gate electrodes, respectively, the gate electrodes being positioned in a first wiring layer from the side of the substrate and arranged separately between the plurality of pixel switching transistors, the gate electrodes are connected to each other through a connection part that is positioned in a second wiring layer from the side of the substrate, and the connection part overlaps with the data wiring when the main surface of the substrate is viewed in plan view.
