In the present embodiment, the cover plate 100 has a substantially rectangular plate shape. The main body 10 of the cover plate 100 is made of a light-transmitting material, and the light-transmitting material may be set according to actual needs, which is not limited herein. The main body 10 is substantially rectangular. The cover plate 100 forms a light-transmitting region corresponding to the region of the body 10. The edge portion 20 is connected to the peripheral side of the main body portion 10. The rim portion 20 is annular. The shielding layer 21 is connected to the periphery of the main body 10, the shielding layer 21 is integrally provided with the main body 10, and the shielding layer 21 is annular. The shielding layer 21 is made of a non-light-transmitting material, and the specific non-light-transmitting material may be set according to actual needs, which is not limited herein. The cover plate 100 forms a non-light-transmitting region corresponding to the region of the shielding layer 21. The material of the shielding layer 21 may have good compatibility with the material of the main body 10, and the shielding layer 21 and the main body 10 may be firmly bonded to form a whole.

The main body portion 10 has a light incident surface 11 and a light emitting surface 12 disposed opposite to the light incident surface 11. The edge portion 20 is provided with a first surface 22 and a second surface 23 arranged opposite to the first surface 22. The first surface 22 is flush with the light incident surface 11. The first surface 22 and the light incident surface 11 form an inner surface 24 of the cover plate 100. The second surface 23 is flush with the light emitting surface 12. The second surface 23 and the light exit surface 12 form an outer surface 25 of the cover plate 100. The inner surface 24 of the cover plate 100 is used for being attached to the optical adhesive layer 91 so as to be fixedly connected with the display screen 92 through the optical adhesive layer 91. Because the first surface 22 is flush with the light incident surface 11, the inner surface 24 forms a smooth surface, and there is no step difference, so that the optical adhesive layer 91 can be completely attached to the inner surface 24, and there is no bad air discharge problem caused by the step difference.

Referring to fig. 2, in the first embodiment, the shielding layer 21 is provided with the first surface 22, and the shielding layer 21 can be attached to the optical adhesive layer through the first surface 22. In the present embodiment, the light incident surface 11 is substantially rectangular. The first surface 22 is connected to the peripheral side of the light incident surface 11, and the first surface 22 is flush with the light incident surface 11. The shielding layer 21 has the first surface 22, and since the first surface 22 and the light incident surface 11 form an inner surface 24 of the cover plate 100, the shielding layer 21 extends from the inner surface 24 to the outer surface 25. The shielding layer 21 is attached to the optical adhesive layer through the first surface 22, that is, the shielding layer 21 may be directly attached to the optical adhesive layer.

Since the second surface 23 and the light emitting surface 12 form the outer surface 25, and the second surface 23 of the shielding layer 21 is a non-light-transmitting surface, the second surface 23 forms a non-light-transmitting portion of the outer surface 25, and the light emitting surface 12 forms a light-transmitting portion of the outer surface 25. By extending the shielding layer 21 from the inner surface 24 to the outer surface 25, the thickness dimension of the shielding layer 21 is substantially the same as the thickness dimension of the main body 10, and the shielding layer 21 can block light passing through the main body 10 from leaking from the peripheral sidewall of the cover plate 100.
