Original Abstract Submitted
A display substrate and a display device are provided, the display substrate includes: a base substrate; a light emitting element, located on the base substrate and including a first electrode, a second electrode, and a light emitting functional layer located between the first electrode and the second electrode; a pixel defining layer, including a pixel defining part and an opening configured to expose at least a part of the first electrode; and a filling layer, located on a side of the second electrode away from the base substrate; the pixel defining part includes a light extraction structure, and a refractive index of the filling layer is greater than a refractive index of the light extraction structure. The display substrate can enhance forward light emission, enhance light extraction effect, and improve light efficiency.
