Abstract
Embodiments of the present disclosure provide a display substrate, a method for manufacturing the same, and a display device, and relate to the field of display technology. The contact area between a first conductive pattern and a second conductive pattern may be increased. The display substrate includes a display area and a peripheral area surrounding the display area. The peripheral area includes a first conductive pattern including at least two first hollow areas as alignment marks, an insulation layer disposed on the first conductive pattern, the insulation layer including a first insulating pattern, the first insulating pattern covering the first hollow area, and the first insulating pattern being incompletely covering space between adjacent first hollow areas, a second conductive pattern disposed on the insulating layer, the second conductive pattern penetrating through the hollow area on the first insulating pattern and electrically connected to the first conductive pattern.
