Abstract
The present disclosure relates to a display substrate and a manufacturing method thereof, and a display device. The display substrate includes a plurality of pixel units each including a first sub-pixel and a second sub-pixel. The method includes: forming a first material layer and a patterned second material layer, the first material layer including a portion corresponding to an area between the first and second sub-pixels, and the second material layer has a first opening exposing the portion of the first material layer, corresponding to the area between the first and second sub-pixels; and forming a first quantum dot solution in a first area corresponding to the first sub-pixel, on the second material layer to form a first color filter sublayer, wherein wettability of the second material layer to the first quantum dot solution is greater than wettability of the first material layer to the first quantum dot solution.
