Abstract
A display substrate, including: a base; a pixel driving circuit and a light-emitting unit sequentially stacked on the base. The light-emitting unit includes a top emission element and a bottom emission element; the top emission element emits light from a side away from the pixel driving circuit; the bottom emission element emits light from a side close to the pixel driving circuit; orthographic projections of an effective light-emitting region of the top emission element and an effective light-emitting region of the bottom emission element on the base do not overlap with each other. The display substrate further includes a reflection reducing structure on a side of the light-emitting unit away from the pixel driving circuit, and an orthographic projection of the reflection reducing structure on the base covers at least the orthographic projection of the effective light-emitting region of the bottom emission element on the base.
