1. An organic light-emitting display substrate, comprising a display area and an opening area located at the display area, wherein the display area comprises:
a base substrate;
a partition pattern layer located on one side of the base substrate and comprising a partition wall disposed around the opening area, wherein the partition wall comprises a wall portion and a blocking portion located on one side of the wall portion away from the base substrate, an orthographic projection of the blocking portion on the base substrate covers an orthographic projection of the wall portion on the base substrate, and an area of the orthographic projection of the blocking portion on the base substrate is greater than an area of the orthographic projection of the wall portion on the base substrate; and
an organic evaporation layer located on one side of the partition pattern layer away from the base substrate, wherein the organic evaporation layer is discontinuous by being blocked by the partition wall;
wherein the display area comprises a plurality of island areas spaced by the opening area, and a bridge area connected between adjacent island areas of the plurality of island areas, wherein each of the plurality of island areas is provided with a pixel area, and the bridge area is provided with a trace area, and
wherein the partition wall is disposed in each of the plurality of island areas and the bridge area, and the partition wall in the bridge area is between the opening area and the trace area.
