The middle portion 21 of the cover plate 20 is located at the center of the cover plate 20, and the arc-shaped edge 22 of the cover plate 20 is connected to the edge of the middle portion 21. In this embodiment, there are two arc-shaped edges 22 of the cover plate 20, and the two arc-shaped edges 22 are symmetrically distributed on two opposite sides of the middle portion 21. Wherein the two arc-shaped edges 22 and the middle part 21 are of an integrally formed structure.
The middle portion 21 of the cover plate 20 includes a bottom surface 211 facing the display panel 10 and a top surface 212 disposed opposite the bottom surface 211. In this embodiment, the intermediate portion 21 is planar. Specifically, the bottom surface 211 and the top surface 212 of the middle portion 21 are disposed in parallel, and both the bottom surface 211 and the top surface 212 of the middle portion 21 are planar. That is, the intermediate portion 21 has a planar plate shape with an equal thickness. Wherein the bottom surface 211 and the top surface 212 of the intermediate portion 21 are both parallel to the X-Y plane.

In one embodiment, the optical adhesive layer 20 is made of a solid clear adhesive (OCA). The elastic modulus of the optical adhesive layer 30 is greater than 100 KPa.

In other words, the rigidity of the optical glue layer 30 is small. That is, the flexibility of the optical adhesive layer 30 is large. In the process of attaching the cover plate 20 to the display panel 10, because the flexibility of the optical adhesive layer 30 is relatively large, part of the optical adhesive layer 30 flows along the inner surface 221 of the arc-shaped edge 22 of the cover plate 20, so that the optical adhesive layer 30 can form the top surface 322 of the edge portion 32 matched with the bottom surface 221 of the arc-shaped edge 22 of the cover plate 20 under the action of the arc-shaped edge 22 of the cover plate 10, thereby eliminating the extrusion force of the arc-shaped edge 22 of the cover plate 20 on the edge portion 104 of the display panel 10, and avoiding the problem that the edge portion 104 of the display panel 10 is badly displayed due to the extrusion force of the arc-shaped edge 22 of the cover plate 20.

Since the optically transparent resin is liquid, the liquid optically transparent resin flows along the inner surface 221 of the arc-shaped edge 22 of the cover plate 20 during the process of attaching the cover plate 20 to the display panel 10, and after the optically transparent resin is cured, the optical adhesive layer 30 can form the top surface 322 of the edge portion 32 matching with the bottom surface 221 of the arc-shaped edge 22 of the cover plate 20 under the action of the arc-shaped edge 22 of the cover plate 10, so as to avoid the problem that the edge portion 104 of the display panel 10 is badly displayed due to the extrusion force of the arc-shaped edge 22 of the cover plate 20.
In this embodiment, the top surface 322 of the edge portion 32 of the optical adhesive layer 30 is processed into the curved surface matching with the bottom surface 221 of the arc-shaped edge 22 of the cover plate 20, so as to ensure that the top surface 322 of the edge portion 32 of the optical adhesive layer 30 can completely adhere to the bottom surface 221 of the arc-shaped edge 22 of the cover plate 20, when the cover plate 20 is adhered to the display panel 10, the arc-shaped edge 22 of the cover plate 20 cannot extrude the edge portion 104 of the display panel 10 through the edge portion 32 of the optical adhesive layer 30, so as to eliminate the extrusion force of the arc-shaped edge 22 of the cover plate 20 on the display panel 10, reduce the probability that the edge portion 104 of the display panel 10 is damaged due to extrusion by the arc-shaped edge 22 of the cover plate 20, avoid the problem that the display panel 10 is cracked, yellowed, generates bubbles or red and blue spots, and the like, and ensure the display quality of the display panel 10.
