Abstract

A display substrate and a manufacturing method therefor, and a display device. In the display substrate, a pixel defining layer comprises a first pixel aperture and a first isolation aperture, the first pixel aperture is located on the side of a first electrode of a first light-emitting element distant from a base substrate and exposes at least part of the first electrode, and the first isolation aperture is located on the periphery of the first pixel aperture; the pixel defining layer comprises a first pixel defining portion located between the first pixel aperture and the first isolation aperture and a second pixel defining portion located on the side of the first isolation aperture distant from the first pixel aperture; and the first pixel defining portion comprises a first main body portion and a first compensation portion which are connected, the first compensation portion is located on the side of the first main body portion close to the first isolation aperture, and the first compensation portion is provided with a first protruding contour protruding from the top of the first main body portion in a direction away from the base substrate, so that the maximum height of the first compensation portion is greater than the maximum height of the first main body portion. Therefore, the display substrate can avoid dark spots and color casts.
