s20, enabling the flexible substrate to be in a first state, and adhering a first structural layer to the display module and/or the side of the flexible substrate opposite to the display module by adopting an adhesive layer, wherein the adhesive layer is at least positioned between the first structural layer and the display module and/or between the first structural layer and the flexible substrate; and
s30, enabling the flexible substrate to be in a bent state, and carrying out curing treatment on the adhesion layer to form the flexible display device.
2. The method of claim 1, wherein the first state is the bent state, and a bending angle of the bent state is greater than 0 ° and less than 180 °.
3. The method of claim 2, wherein the first structural layer comprises a touch layer and a cover plate adhered to the display module, and a protective layer adhered to a side of the flexible substrate facing away from the display module.
4. The method of claim 1, wherein the first state is a planar state, and the first structural layer comprises a touch layer and a cover plate adhered to the display module, and a protective layer adhered to a side of the flexible substrate facing away from the display module.
5. The method for manufacturing a flexible display device according to claim 1, wherein the first state is a planar state, and the step S30 further comprises: and conformally adhering a second structural layer to the first structural layer and/or the side of the flexible substrate, which faces away from the display module, by using the adhesion layer, wherein the adhesion layer is also at least positioned between the second structural layer and the first structural layer and/or between the second structural layer and the flexible substrate.
6. The method as claimed in claim 5, wherein the first structural layer comprises a touch layer adhered to the display module and a protective layer adhered to a side of the flexible substrate facing away from the display module, and the second structural layer comprises a cover plate adhered to the touch layer.
7. The method for manufacturing the flexible display device according to claim 1, wherein a bending direction of the bent state is the same as a bending direction of the flexible display device.
8. The method of claim 1, wherein the curing process comprises a thermal curing process or an ultraviolet curing process.
9. The method of claim 1, wherein the adhesive layer comprises a transparent optical glue.
10. A flexible display device, comprising:
a flexible substrate in a bent state;
a display module conformally disposed on the flexible substrate;
a functional module conformally disposed on the display module and/or on the flexible substrate; and
an adhesive layer conformally disposed between adjacent film layers of the functional module, and between the functional module and the display module and/or between the functional module and the flexible substrate.
