Abstract
A pixel array substrate includes a pixel driving circuit, a first insulating layer, a pad group, and an adjustment structure. The first insulating layer is disposed on the pixel driving circuit. The pad group is electrically connected to the pixel driving circuit. The adjustment structure is disposed on the first insulating layer and is electrically connected to the pad group. The adjustment structure is located between the pad group and the pixel driving circuit. The adjustment structure includes a first adjustment part and a second adjustment part. At least a part of the first adjustment part overlaps the pad group. The second adjustment part is disposed outside the first adjustment part and is staggered from the pad group. An absorptance of the first adjustment part to a laser is higher than an absorptance of the second adjustment part to the laser.
