1. A display panel having a main display region and a functional device region, the main display region being located at at least part of sides of the functional device region, and a light transmittance of the main display region being less than a light transmittance of the functional device region;
the display panel comprising a plurality of first pixel circuits and a plurality of redundant pixel circuits, wherein the plurality of first pixel circuits are located in the main display region, first pixel circuits are arranged in a row of first pixel circuits in a first direction, a plurality of rows of first pixel circuits are arranged in a second direction, and the first direction intersects with the second direction; wherein
the display panel comprises a substrate, and an active layer and an anode layer that are arranged on the substrate in sequence in a direction perpendicular to the substrate and away from the substrate; wherein
the plurality of redundant pixel circuits include at least a column of redundant pixel circuits arranged in the second direction, and the column of redundant pixel circuits is located between the functional device region and a column of first pixel circuits; a redundant pixel circuit includes at least redundant active layer patterns located in the active layer, and the redundant pixel circuit is electrically insulated from the anode layer; redundant active layer patterns in two adjacent redundant pixel circuits are same, and are separated from each other.
