Display substrate and electrostatic discharge device and method

The embodiment of the invention relates to the technical field of display device manufacturing, and discloses a display substrate, which comprises a substrate and a plurality of display areas locatedon the substrate. Each display area comprises a plurality of pixel units; the substrate is also provided with a capacitor, a plurality of discharge wires, a first lead, a second lead, and a first discharge metal and a second discharge metal which are located at the edge of the substrate and are not conducted with each other. The plurality of pixel units are connected to the capacitor in parallel through a plurality of discharge wires, and each pixel unit is correspondingly connected with one discharge wire; one end of the capacitor is connected to the first discharge metal through a first lead, and the other end of the capacitor is connected to the second discharge metal through a second lead. The first discharge metal and the second discharge metal are used for being externally connectedwith a grounding conductor
