Preferably, the shape of each minimal repeating unit of the grid-like structure having openings formed by all the first supports 26 is the same. The first supporting bodies 26 are separated from each other and are not connected with each other, so that a grid-shaped structure with openings is formed, and the optical cement can be allowed to flow through the openings before curing when the optical cement layer 23 is manufactured, so that the smoothness of fit between the flexible glass layer 22 and the protective material layer 24 is improved; after the manufacture is finished, the optical cement can be limited in the grid-shaped structure with the openings, so that the fluidity of the optical cement is reduced, and the purpose of reducing the deformation of the optical cement layer 23 is achieved.
