In the present application, the first flexible substrate, the second flexible substrate, and the third flexible substrate can be different parts of a whole flexible substrate. The first array layer, the second array layer, and the wiring layer can be different parts of a same thin film transistor array layer.

As shown in FIG. 2, when the elastic substrate 10 is in the natural state, the connecting portions 40 are accommodated in the accommodating spaces 23 enclosed by the first main bodies 22 of the main pixel islands 20, thereby preventing the connecting portions 40 from blocking the main pixel units 21 on the main pixel islands 20, and also preventing the connecting portions 40 from being squeezed by the adjacent main pixel islands 20.

When the flexible display panel 100 is stretched from the natural state, the connecting portions 40 are gradually exposed from the accommodating spaces 23 and are stretched and straightened. The elastic substrate 10 in the flexible display panel 100 has good elasticity and provides elasticity for restoring deformation. The connecting portions 40 stop being stretched after the connecting portions 40 are straightened by gradually stretching, so as to ensure that metal lines in the connecting portions 40 do not break by stretching.
