Abstract
A display substrate includes a substrate, and first active layers, a first functional layer, a second active layer, a second functional layer and an interlayer dielectric layer stacked in sequence on the substrate. The display substrate further includes first vias, second vias and third vias. The first vias each penetrate at least a portion of the second functional layer and at least a portion of the first functional layer, and each expose a partial surface of a first active layer. The second vias each penetrate the interlayer dielectric layer, and are respectively communicated with the first vias. The third vias each penetrate the interlayer dielectric layer and at least another portion of the second functional layer, and each expose a partial surface of the second active layer. The first vias are formed before the interlayer dielectric layer, and the third vias are formed later than the interlayer dielectric layer.
