摘要： A display substrate, a method for manufacturing the same, and a display device are provided. The display substrate includes a base substrate, and a drive circuit layer disposed on the base substrate, the display substrate having an active area and a fan-out area, the drive circuit layer being provided with a crack-stopping groove therein, the crack-stopping groove being located between the active area and the fan-out area. According to the embodiments of the present disclosure, with the crack-stopping groove provided between the active area and the fan-out area, in the case where a crack occurs in a structure in the active area of the display substrate, the crack is prevented from extending to the fan-out area by isolation of the crack-stopping groove, thereby reducing the possibility of structures in the fan-out area of the display panel being damaged and improving the reliability of the display panel.
