Abstract
A display substrate, a manufacturing method thereof, and a display device are provided. The display substrate includes a base substrate, a sub-pixel unit, a data line, a scan line, a plurality of test contact pads, a first peripheral-zone insulating layer and an auxiliary electrode layer. The base substrate includes a display zone and a peripheral zone, the peripheral zone including a test bonding zone. Each of the plurality of the test contact pads includes a first test-contact-pad metal layer and a second test-contact-pad metal layer, wherein the second test-contact-pad metal layer covers the first test-contact-pad metal layer and contacts the first test-contact-pad metal layer in at least portion of a periphery of the first test-contact-pad metal layer. The auxiliary electrode layer includes a plurality of first relay electrode patterns located within the test bonding zone and a plurality of auxiliary electrodes located within the display zone.
