It will be appreciated that when the flexible display panel 20 is in a three-dimensional curved surface or other bending shape after finishing the shaping process, the viscosity of the anti-adhesive layer 102 needs to be reduced by specific conditions, so that the flexible display panel 20 can be easily peeled from the shaping device 10, and in order to avoid peeling between the anti-adhesive layer 102 and the shaping layer 101 during peeling, the adhesion between the anti-adhesive layer 102 and the shaping layer 101 needs to be greater than the adhesion between the anti-adhesive layer 102 and the flexible display panel 20.
