A sealing layer 4 is disposed between the first substrate 1 and the second substrate 2, the sealing layer 4 includes a sealant, and if the sealing layer 4 is made of a photo-curable adhesive and/or a thermosetting adhesive, the sealing layer is used to connect the first substrate 1 and the second substrate 2, and forms a sealed space with the alignment layer 3, the sealed space can be used to contain liquid crystal, and it can be known that alignment grooves are disposed on the alignment layer 3, and the alignment grooves can be used to contain the liquid crystal.
The alignment layer 3 is formed with a hollow area 33, a portion of the sealing layer 4 is located in the hollow area 33, and since the sealing layer 4 can be located in the hollow area 33, a contact area between the sealing layer 4 and the alignment layer 3 is increased compared with a contact area when the hollow area 33 is not disposed, so that an adhesive force between the sealing layer 4 and the alignment layer 3 is increased. Illustratively, the material of the alignment layer 3 may include polyimide.
