Abstract
A display substrate, a manufacturing method thereof and a display device are provided. The display substrate includes a base substrate and a plurality of sub-pixels on the base substrate. Each sub-pixel includes a light-emitting functional layer. A defining structure is provided between adjacent sub-pixels and includes a first sub-structure and second sub-structure stacked. Along an arrangement direction of adjacent sub-pixels, an edge of the second sub-structure protrudes relative to an edge of the first sub-structure to form a protruding portion; or, a side surface of the second sub-structure has a first slope angle, a side surface of the first sub-structure has a second slope angle, and at least one of the first slope angle and the second slope angle is greater than 60 degrees, and at least one of film layers included in the light-emitting functional layer is disconnected at the defining structure.
