Flexible display substrate and method for manufacturing the same

A method for manufacturing a flexible display substrate, comprising:

• forming a first insulating layer on a flexible base substrate, the first insulating layer at least covering a bending area of the flexible display substrate;
• forming an etching barrier layer on a side of the first insulating layer away from the flexible base substrate, the etching barrier layer being located in the bending area;
• forming a second insulating layer covering the etching barrier layer on the side of the first insulating layer away from the flexible base substrate;
• and
• forming a first opening in the first insulating layer and a second opening in the second insulating layer through one patterning process, so that the first opening and the second opening are both located in the bending area, and an orthographic projection of the first opening on the flexible base substrate falls within an orthographic projection of the second opening on the flexible base substrate, so as to form a step portion at a connection position where the first opening is connected to the second opening.
