A display substrate having a display area and a peripheral area, comprising: a base substrate (BS-A); and a barrier layer on the base substrate (BS-A) in the peripheral area comprising a plurality of barriers, each of the plurality of barriers has a first side proximal to an interface between the display area and the peripheral area and a second side distal to the interface between the display area and the peripheral area; the first side having a first undulating shape; the second side having a second undulating shape; wherein each of the plurality of barriers comprises a plurality of barrier segments (1, 1') arranged substantially in a direction parallel to the interface between the display area and the peripheral area, two adjacent barrier segments (1, 1') of each of the plurality of barriers are spaced apart from each other forming an opening (O, O') between the two adjacent barrier segments (1, 1') of each of the plurality of barriers; each of the plurality of barrier segments (1, 1') of each of the plurality of barriers comprises a bend (B, B') protruding towards the interface between the display area and the peripheral area, thereby forming a convex surface on the first side and a concave surface on the second side in each of the plurality of barrier segments (1, 1') of each of the plurality of barriers; characterized in that, the display substrate is an array substrate comprising a conductive layer in the peripheral area; the plurality of barriers comprises a first barrier and a second barrier; the projection of the first barrier on the base substrate (BS-A) being outside the projection of the conductive layer on the base substrate (BS-A); the projection of the second barrier on the base substrate (BS-A) overlapping with the projection of the conductive layer on the base substrate (BS-A); the conductive layer has a plurality of protrusions alternating with a plurality of indentations along a side proximal to the interface between the display area and the peripheral area, the plurality of protrusions protruding in a direction from the peripheral area to the display area, the plurality of indentations indented in a direction from the display area to the peripheral area; adjacent protrusions spaced apart by an indentation; the array substrate further comprises a plurality of common electrode signal lines; each of the plurality of common electrode signal lines extending from an apex of each of the plurality of protrusions into the display area for providing a common voltage; and a plurality of openings (O, O') in the first barrier and the second barrier are substantially aligned with the plurality of indentations. a base substrate (BS-A); and a barrier layer on the base substrate (BS-A) in the peripheral area comprising a plurality of barriers, each of the plurality of barriers has a first side proximal to an interface between the display area and the peripheral area and a second side distal to the interface between the display area and the peripheral area;
