1. A display panel, comprising:
a rigid substrate;
a flexible substrate on a side of the rigid substrate;
wherein the flexible substrate comprises a plurality of through-groove structures, and at least one of the plurality of through-groove structure comprises a non-fixed region and a fixed region surrounding the non-fixed region; and
an encapsulation layer on a side of the flexible substrate facing away from the rigid substrate;
wherein a portion of the encapsulation layer in the at least one of the plurality of through-groove structure comprises a first sub-portion in the fixed region and attached to the rigid substrate and a second sub-portion in the non-fixed region and attached to the rigid substrate via an organic separation layer;
the second sub-portion is configured to be separated from the rigid substrate in a case of gasification of the organic separation layer; and
the first sub-portion is configured to be lifted off from the flexible substrate together with the rigid substrate under an external force.
