Abstract
A display substrate, a manufacturing method thereof, and a display panel. The display substrate includes a base, a first electrode, a first auxiliary cathode, a second electrode and a second auxiliary cathode, a pixel definition layer and a cathode. The first and second electrodes are located in the display area and the first and second auxiliary cathodes are located in the non-emitting area. The orthogonal projections of the first auxiliary cathode and the second auxiliary cathode on the base are in a mesh structure. The pixel definition layer is at least located in the non-emitting area. The cathode at least covers the display area and the cathode is arranged on one side of the pixel definition layer far away from the base; wherein the cathode, the first auxiliary cathode and the second auxiliary cathode are electrically connected.
