Provided are a display substrate and a preparation method therefor, and a display device. Since a quantum dot light-emitting device where a quantum dot light-emitting layer is located is made of the same quantum dot material, and the quantum dot light-emitting layer is integratedly arranged on the same layer, there is no need to conduct patterning on the quantum dot light-emitting layer, thereby avoiding the problem of colour offset in the prior art caused by adopting different quantum dot materials. |
