Abstract: The present invention provides a display substrate and a manufacturing method thereof, and a flexible display device having the display substrate, which belong to the field of display technology, and can solve the problem of poor reliability of display substrates due to the damage to thin film transistors when the existing display substrates are bent. In the display substrate provided by the present invention, by introducing stress absorption units made of resin material into the display substrate, the stress generated by the display substrate being bent is released by the resin material, and thin film transistors on the display substrate are thus less likely to be damaged, so that the reliability of the whole display substrate is improved.
