    Abstract: The disclosure provides a display substrate, a manufacturing method thereof and a display device. The display substrate has a plurality of subpixel regions. The display substrate includes a base substrate and a pixel definition layer on the base substrate. The pixel definition layer defines a plurality of subpixel openings and each of the subpixel openings occupies one subpixel region. The display substrate further includes a functional medium layer on a side of the pixel definition layer away from the base substrate. The functional medium layer includes a first portion covering side surfaces of the subpixel opening and a second portion covering a top surface of the pixel definition layer. In the same subpixel region, surface energy of the first portion is greater than surface energy of the second portion.
