A display device comprises a first electrode of a (1-1)-th subpixel, a first electrode of a (1-2)-th subpixel, a first electrode of a (2-1)-th subpixel, and a first electrode of a (2-2)-th subpixel; a (1-1)-th welding electrode connected to the first electrode of the (1-1)-th subpixel, a (1-2)-th welding electrode connected to the first electrode of the (1-2)-th subpixel, a (2-1)-th welding electrode connected to the first electrode of the (2-1)-th subpixel, and a (2-2)-th welding electrode connected to the first electrode of the (2-2)-th subpixel; and a first repair line overlapping the (1-1)-th welding electrode and the (2-1)-th welding electrode and a second repair line overlapping the (1-2)-th welding electrode and the (2-2)-th welding electrode, wherein the first repair line and the second repair line are disposed on different layers with at least one insulating layer interposed therebetween.

Provided are a backplane and a display device. The backplane comprises an active area, a first binding area and a second binding area. The first binding area is detachably disposed on a side of the second binding area away from the active area, and both the first binding area and the second binding area are capable of being bonded to an external electronic assembly. By arranging two binding areas, if there is a defective product in a module process, the first binding area is detached, and the second binding area is attached to the external electronic assembly, such that the display device is repaired in the module process, thereby reducing a scrapping cost of the product.
