Abstract: A stretchable display panel and a method for manufacturing same, and a display apparatus, which belong to the technical field of display. The method comprises: forming an organic protection structure (100) and an inorganic protection structure (200), which are stacked, on a rigid substrate (000); forming a flexible substrate (300) on the inorganic protection structure (200); forming, on the flexible substrate (300), a plurality of pixel islands and inter-island connection pieces for connecting adjacent pixel islands; forming package layers on the pixel islands and the inter-island connection pieces; and lifting off the rigid substrate (000). The package layers are not in contact with the rigid substrate (000), but the organic protection structure (100) is always in contact with the rigid substrate (000). It is extremely easy for the organic protection structure (100) to be lifted off from the rigid substrate (000), and the probability of a crack occurring during the lifting-off process is relatively low, thereby effectively reducing the probability of package failure of the package layers, and further prolonging the service life of light-emitting devices in the pixel islands.
