Abstract
A display substrate and a display device are disclosed. In the display substrate, each sub-pixel includes: a conductive light-shielding structure; a buffer layer; a semiconductor layer; an interlayer insulating layer, located on a side of the semiconductor layer away from the buffer layer; and a conductive layer, located on a side of the interlayer insulating layer away from the semiconductor layer, and including a conductive structure. The conductive light-shielding structure includes a first main body portion and a first recessed portion, an average thickness of the first recessed portion is smaller than an average thickness of the first main body portion. The display substrate further includes a first contact hole, the first contact hole penetrates both the interlayer insulating layer and the buffer layer, the conductive structure is electrically connected with the first recessed portion through the first contact hole.
