Abstract: A flexible display substrate and a manufacturing method therefor, and a display apparatus, for relieving the problem that it is difficult to bend the flexible display substrate in a bending region to damage an upper circuit. The flexible display substrate comprises a back film, a first flexible base substrate located above the back film, and a second flexible base substrate located on one side of the first flexible base substrate facing away from the back film. The flexible display substrate has a bending region. An auxiliary layer is further provided between the first flexible base substrate and the second flexible base substrate. At least part of the auxiliary layer in the bending region can be decomposed in a preset condition, wherein the other film layers except the auxiliary layer are maintained at the original status in the preset condition.
