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.
