Abstract: The present disclosure provides a display substrate and a manufacturing method thereof, and a display panel. The method includes: providing a base substrate; forming a quantum dot material layer on the base substrate by using a mixture of a quantum dot material and ester compounds; enabling the ester compounds in the quantum dot material layer to react by a sol-gel method to form a sol-gel layer that is doped with nanoparticles; performing a curing processing on the sol-gel layer to obtain a quantum dot color film layer.
