    Abstract: A display substrate, including a base substrate, a plurality of pixel units, and a pixel definition layer. The pixel unit includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The fourth sub-pixel is a white sub-pixel, and any two of the first sub-pixel, the second sub-pixel, the third sub-pixel and the fourth sub-pixel display different colors. In at least one pixel unit, at least one of the first sub-pixel, the second sub-pixel and the third sub-pixel is located in a different row from the fourth sub-pixel. In at least one pixel unit, each of orthographic projections of a first opening of the first sub-pixel, a second opening of the second sub-pixel and a third opening of the third sub-pixel on the base substrate has an area less than that of a fourth opening of the fourth sub-pixel on the base substrate.

    Abstract: A display panel has a display area and a frame area located at at least one side of the display area. The display panel includes a base, at least one groove, a plurality of light-emitting devices, at least one first fixing component, and a sealant disposed at least in the frame area. At least one groove is arranged at a side of the base, and the at least one groove is located in the frame area. Each first fixing component includes a first portion and a second portion, and the first portion of the first fixing component is embedded in a groove. The sealant is located at the side of the base having the at least one groove, and the second portion of the first fixing component is embedded in the sealant.

    Abstract: A pixel definition layer and a manufacturing method thereof, a display substrate, and a display panel are provided. The pixel definition layer includes: a lyophilic material layer on a base substrate, which includes a plurality of lyophilic portions spaced in pairs, which being with an annular structure and used to define a pixel region; and a lyophobic material layer on a side of the lyophilic material layer from the base substrate, which being filled between each two adjacent lyophilic portions of the plurality of lyophilic portions, and a distance from a surface of the lyophobic material layer from the base substrate to the base substrate is larger than a distance from a surface of the lyophilic material layer from the base substrate to the base substrate. The pixel definition layer improves the uniformity of films formed in the pixel region by the solution.
