Abstract: Provided are a display panel and a manufacturing method thereof and a display device. The display panel includes: a base substrate; a pixel defining layer including first openings defining sub-pixels; an encapsulation layer; and a light modulation layer. The light modulation layer is configured such that light from each of at least one sub-pixel propagates along a direction away from the base substrate after total reflection upon incidence on an interface between the first light modulation portion in a corresponding second opening and the first light modulation sub-layer. The display panel satisfies at least one of a first condition or a second condition. The first condition is that at least a part of edge of the first orthographic projection has a recess. The second condition is that at least a part of edge of the second orthogonal projection has at least one of a recess or a protrusion.

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.
