1. A display panel, wherein the display panel comprises a plurality of subpixels, and each of the plurality of subpixels comprises an active layer, a source, an anode, and a repair electrode disposed on a substrate, wherein the source is located between the active layer and the anode, and the repair electrode is connected to the source and located on a side of the active layer close to the anode; and
wherein with respect to two adjacent subpixels, an orthographic projection of the repair electrode of one subpixel of the two adjacent subpixels on the substrate partially overlaps with an orthographic projection of the anode of the other subpixel of the two adjacent subpixels on the substrate,
wherein the anode has an extension portion, and wherein in a direction parallel to a plane in which the substrate is located, with respect to the two adjacent subpixels, the repair electrode of the one subpixel extends toward the extension portion of the other subpixel, the extension portion of the other subpixel extends toward the repair electrode of the one subpixel, and the orthographic projection of the repair electrode of the one subpixel on the substrate partially overlaps with an orthographic projection of the extension portion of the other subpixel on the substrate,
wherein with respect to the two adjacent subpixels, the repair electrode of the one subpixel is disposed in the same layer as the source, and extends from one end of the source toward the extending portion of the other subpixel,
wherein the display panel further comprises a passivation layer, a protection electrode, and a planarization layer sequentially disposed between the source and the anode, and wherein a contact hole is formed in the passivation layer, the protection electrode is connected to the source through the contact hole, a via hole communicating with the contact hole is formed in the planarization layer, and the anode is connected to the protection electrode through the via hole; and
wherein an orthographic projection of the protection electrode on the plane in which the substrate is located at least partially overlaps with the orthographic projection of the repair electrode on the plane in which the substrate is located.
