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.
