Display device

A display device comprising:

• a panel substrate including a layered region and a display region, the layered region including a layered wiring structure of a plurality of layers;
• a plurality of video signal lines provided on the panel substrate;
• a potential supply line that supplies a predetermined potential to each of the plurality of video signal lines;
• and
• a plurality of external connecting terminals, provided on the panel substrate, for receiving supply of video signals to be applied to the plurality of video signal lines, wherein
• the plurality of video signal lines are provided to extend from the plurality of external connecting terminals into the display region via the layered region, and
• in the layered region, two video signal lines adjacent in a vertical direction are a combination of a video signal line of an odd-numbered column and a video signal line of an even-numbered column, and two video signal lines adjacent in a horizontal direction in a same layer of the plurality of layers are a combination of a video signal line of an odd-numbered column and a video signal line of an even-numbered column.
