The manufacturing method of the present embodiment includes the steps of:

step 101: the inner surface of the curved substrate 12 is provided with a double-sided adhesive tape 200, wherein a release paper 201 is adhered to one surface of the double-sided adhesive tape 200 far away from the inner surface.

In this step, the double-sided tape 200 is divided into two sections, and is respectively adhered to the inner surfaces of the first body portion 121 and the second body portion 122.

Similarly, the release paper 201 is divided into two sections, and is adhered to the surfaces of the double-sided tapes 200 of the first body portion 121 and the second body portion 122.

The release paper 21 has a length greater than twice that of the double-sided adhesive tape 200, and is disposed on a surface of the double-sided adhesive tape 200 away from the inner surface of the curved substrate 12 in a folded manner. The number of folds is one.
