摘要： The invention provides a display substrate, a manufacturing method thereof and a flexible display device. The display substrate in the present invention includes a base substrate and a vulnerable member arranged on the base substrate, as well as a stress absorption layer arranged between the base substrate and the vulnerable member, wherein the projection of the vulnerable member on the base substrate is within the projection region of the stress absorption layer on the base substrate; the stress absorption layer is not arranged on part of the base substrate. Since the display substrate and the flexible display device provided by the present invention are provided with the stress absorption layer, stress generated during bending may be dispersed through the stress absorption layer to protect the vulnerable member from being damaged, so as to improve the reliability of the display substrate and the flexible display device.
