A light-emitting substrate and a manufacturing method thereof are disclosed. In the embodiment of the present disclosure, by providing a groove on a base plate in the manufacturing method of the light-emitting substrate, the accuracy of coating the solder resist ink layer can be improved so as to reduce a distance between the solder resist ink layer and the pad assembly and avoid poor soldering or soldering failure caused by the overflow of the solder resist ink onto the pad.
