Abstract: A display substrate includes a light emitting element on a base substrate; and a light modulating structure on a side of the light emitting element away from the base substrate. The light modulating structure includes a color filter layer and a substantially transparent layer on a side of the color filter layer away from the base substrate. The color filter layer includes a plurality of color filter units, a respective color filter unit of the plurality of color filter units being in an individual subpixel. Adjacent color filter units are spaced apart by a portion of the substantially transparent layer that extends into a region between the adjacent color filter units. An orthographic projection of the respective color filter unit on the base substrate at least partially overlaps with an orthographic projection of a light emitting layer of the light emitting element on the base substrate.
