Abstract
Provided are a display substrate, a method for detecting the same and a display device. The display substrate includes a display area and a non-display area surrounding the display area, the display substrate further includes data lines extending from the display area to the non-display area, the non-display area is provided with at least one switching transistor, a first electrode of each switching transistor is coupled to one of the data lines, a second electrode of each switching transistor is coupled to a data voltage supply circuit, at least one crack detecting wire, corresponding to the at least one switching transistor in one-to-one correspondence, is provided in the display area, an end of the crack detecting wire is coupled to a control electrode of the switching transistor corresponding to the crack detecting wire, another end of the crack detecting wire is coupled to a switching voltage supply circuit.
