Display panel, pixel array substrate and line array structure

A pixel array substrate, comprising:

• a substrate, having a first region, a second region and a drive connection region, wherein the first region has first sides that extend along a long-side direction and second sides that extend along a short-side direction, the second region protrudes out from the first sides and is connected to the first region, the drive connection region is connected to the second side of the first region;
• a pixel array, disposed on the substrate, wherein the pixel array comprises:
• a plurality of pixel structures, disposed in the first region and the second region, wherein each of the pixel structure comprises a pixel electrode and an active device;
• a plurality of first signal lines and a plurality of second signal lines, wherein each of the pixel structures is electrically connected to one of the first signal lines and one of the second signal lines, and the first signal lines and the second signal lines are used to drive the pixel structures, wherein the first signal lines or the second signal lines comprise a plurality of long wirings and a plurality of short wirings, the long wirings are disposed in the first region and are parallel with the long-side direction and extend to the drive connection region, and the short wirings are disposed in the second region, and are parallel with the long wirings;
• a plurality of first dummy wirings, disposed in the first region, and are parallel with the long-side direction and extend to the drive connection region;
• and
• a plurality of first connection lines, wherein each of the short wirings is electrically connected to a corresponding first dummy wiring through one of the first connection lines.
