摘要： A display substrate includes a backplane, a pixel defining layer, a gas absorption layer, and light-emitting layers. The pixel defining layer is disposed on a side of the backplane, and has a plurality of openings. The gas absorption layer is disposed on a side of the pixel defining layer away from the backplane, and is configured to absorb a gas generated by the pixel definition layer due to an action of ultraviolet rays. The gas absorption layer exposes at least part of regions of the plurality of openings. The light-emitting layers are each at least partially located in an opening in the plurality of openings.
