1. An array substrate, comprising:
a base substrate comprising a display region and a peripheral region located at a periphery of the display region;
a first conductive layer located on the base substrate; and
an organic layer located at a side of the first conductive layer away from the base substrate, wherein
the peripheral region comprises at least one bonding region, and in each of the at least one bonding region, the first conductive layer comprises a plurality of wires arranged at intervals, and the organic layer comprises a first opening exposing the plurality of wires; and
the first opening comprises an edge that is intersected with an extension direction of each of the plurality of wires; the organic layer further comprises a zigzag-shaped groove connected with the edge; in a direction perpendicular to the base substrate, a depth of the zigzag-shaped groove is smaller than a thickness of the organic layer; and an orthographic projection of the zigzag-shaped groove on a plane parallel with the base substrate is zigzag-shaped, wherein
the zigzag-shaped groove comprises a plurality of triangular grooves arranged along the edge of the first opening, wherein each of the plurality of triangular grooves comprises a bottom side and a vertex angle opposite to the bottom side, the bottom side is overlapped with the edge of the first opening, and the vertex angle is located at a side of the bottom side away from the first opening,
a width of each of the wires is D1, a distance between two adjacent wires is D2, and a length of the bottom side of the triangular groove is (D1+D2)/2, and
the organic layer further comprises a plurality of interval regions located between adjacent triangular grooves, and neither orthographic projections of the plurality of triangular grooves nor orthographic projections of the plurality of interval regions on a first plane perpendicular to the base substrate and parallel to an extending direction of the wire are overlapped with orthographic projections of portions of the plurality of wires exposed through the first opening on the first plane.
