Abstract
A pixel defining layer, a display substrate and manufacturing method thereof, and a display apparatus are provided. The pixel defining layer includes: a lyophilic material layer disposed on a base substrate, and a lyophobic material layer disposed at a side of the lyophilic material layer away from the base substrate. An orthographic projection of a surface of the lyophobic material layer close to the base substrate on the base substrate is within an orthographic projection of a surface of the lyophilic material layer away from the base substrate on the base substrate. The lyophilic material layer is made of a lyophilic material having attractability to a solution with organic electroluminescent materials dissolved, and the lyophobic material layer is made of a lyophobic material having repellency to the solution with organic electroluminescent materials dissolved. The pixel defining layer reduces the influence on the uniformity of the films.
