Abstract: Provided are a display panel and a manufacturing method thereof and a display device. The display panel includes: a base substrate; a first planarization layer; a plurality of sub-pixels, a plurality of anodes of which being located on one side of the first planarization layer away from the base substrate; a pixel defining layer having a plurality of pixel openings; a planarization structure including a plurality of planarization portions, orthographic projection of each of the first group of pixel openings on the base substrate is a first orthographic projection, orthographic projections of an anode and a planarization portion corresponding to each of the first group of pixel openings on the base substrate are a second and a third orthographic projection respectively, and an overlapping portion of the first and second orthographic projections is located within the third orthographic projection.

Abstract: Provided are a display substrate, a preparation method thereof, and a display apparatus. The display substrate includes a flexible substrate, a driving structure layer disposed on the flexible substrate, a light-emitting element disposed on the driving structure layer, and an encapsulation layer disposed on the light-emitting element. The flexible substrate includes a first flexible substrate layer, a first connection layer disposed on the first flexible substrate layer, and a second flexible substrate layer disposed on the first connection layer, wherein, the first connection layer includes at least one first via, and the first flexible substrate layer includes at least one first groove provided corresponding to the first via; the first via and the first groove are mutually communicated, and an orthographic projection of the first groove on the first flexible substrate layer includes an orthographic projection of the first via on the first flexible substrate layer.

Abstract: A display motherboard includes a motherboard body, wherein n recess structures for guiding the motherboard body to fracture are provided on a surface of the motherboard body, n being greater than 1; wherein the n recess structures are arranged in sequence and centers of the n recess structures are collinear.
