A flat liquid crystal panel generally includes a first substrate (array substrate), a second substrate (color filter substrate), and liquid crystal sealed between the first substrate and the second substrate. Fig. 1 is a schematic diagram of a conventional planar liquid crystal panel. The first substrate 100 is provided with a plurality of pad layers 101, the second substrate 200 is provided with a plurality of spacers 201, and when the first substrate 100 and the second substrate 200 are assembled, the pad layers 101 of the first substrate 100 are just opposite to and contacted with the spacers 201 of the second substrate 200, so that the liquid crystal display panel is ensured to have a certain thickness, and the display quality of the liquid crystal display panel is ensured. Fig. 2 is a schematic structural diagram of a conventional liquid crystal panel after bending. When a flat liquid crystal panel is bent for curved display, the curvature of the first substrate 100 is different from that of the second substrate 200, and the stress at each position of the liquid crystal panel is different, so that the first substrate 100 and the second substrate 200 are relatively displaced, and the cushion layer 101 of the first substrate 100 may be dislocated from the spacer 201 of the second substrate 200, so that the contact may not be made, and the box thickness of the liquid crystal panel may be uneven, resulting in poor display.

Detailed Description
The present invention is further illustrated by the following figures and specific examples, which are to be understood as illustrative only and not as limiting the scope of the invention, which is to be given the full breadth of the appended claims and any and all equivalent modifications thereof which may occur to those skilled in the art upon reading the present specification.
Fig. 3 is a schematic diagram of a liquid crystal panel according to an embodiment of the present invention. As shown in fig. 3, the liquid crystal panel of the present invention includes a first substrate 100 and a second substrate 200 that are disposed opposite to each other, wherein the first substrate 100 is an array substrate, the second substrate 200 is a color film substrate, a plurality of spacers 101 are disposed on the first substrate 100, and a plurality of spacers 201 corresponding to the spacers 101 are disposed on the second substrate 200. The spacer 201 is cylindrical and includes an upper bottom surface and a lower bottom surface. When the first substrate 100 and the second substrate 200 are assembled, the pad layer 101 of the first substrate 100 is in contact with the spacer 201 of the second substrate 200 to maintain a certain thickness of the liquid crystal panel. The contact area between the pad layer 101 and the spacer 201 is a fixed value, and the contact area between the pad layer and the spacer shown in fig. 3 is half of the area of the upper bottom surface of the spacer, which may be other values. The contact positions between two adjacent spacers and the corresponding cushion layers are different. As shown in fig. 3, two adjacent spacers are defined as a first spacer 201 and a second spacer 202, respectively, the pad layer in contact with the first spacer 201 is a first pad layer 101, the pad layer in contact with the second spacer 202 is a second pad layer 102, one end of the first pad layer 101 away from the second pad layer 102 is defined as a left end, one end close to the second pad layer 102 is defined as a right end, and similarly, one end of the second pad layer 102 close to the first pad layer 101 is defined as a left end, and one end away from the first pad layer 101 is defined as a right end. The contact position between the first spacer 201 and the first pad layer 101 is close to the left end of the first pad layer 101, the contact position between the second spacer 202 and the second pad layer 102 is close to the right end of the second pad layer 102, and so on, so that the contact positions between two adjacent spacers and the corresponding pad layers are different. Fig. 4 is a schematic diagram illustrating a distribution of spacers and spacers of a liquid crystal panel according to an embodiment of the invention. As shown in fig. 4, the spacers are partially in contact with the pad layers, and the contact positions between two adjacent spacers and the corresponding pad layers are different. Fig. 5 is a schematic structural diagram of a liquid crystal panel after bending according to an embodiment of the invention. When the liquid crystal panel is used for curved surface display after being bent, because the curvatures of the first substrate 100 and the second substrate 200 are different, the stress at each position of the liquid crystal panel is different, so that the relative displacement between the cushion layer on the first substrate 100 and the spacer on the second substrate 200 is caused, part of cushion layers are separated from the contact with the spacers, but part of cushion layers can be still ensured to be in contact with the spacers, and the integral box thickness of the curved surface liquid crystal panel is ensured to be consistent.
Fig. 6 is a schematic diagram of a liquid crystal panel structure according to a second embodiment of the present invention. The difference between the liquid crystal panel provided in the second embodiment and the first embodiment is that the spacer 203 located in the central region of the liquid crystal panel is completely in contact with the pad layer 103 along the center of the pad layer 103, and the spacers located in the two end regions of the liquid crystal panel are in partial area contact with the pad layer. Fig. 7 is a schematic structural diagram of a liquid crystal panel according to a second embodiment of the present invention after being bent. After the liquid crystal panel is bent, the contact between partial quantity of spacers and the cushion layer can be still ensured, and in the central area of the panel, because the displacement does not occur, the density of the spacers is greater than that of the spacers at the two ends of the panel, so that the spacers in the central area of the liquid crystal panel can bear larger stress than the spacers at the two ends of the liquid crystal panel, and the equal spacing can be kept between the first substrate and the second substrate, thereby ensuring the integral box thickness of the curved liquid crystal panel to be consistent, and further improving the optical taste of the curved liquid crystal panel.
The liquid crystal panel of the present invention is not limited to the use for curved display, and can be applied to flat display.
According to the invention, the spacers and the cushion layer are designed to be partially contacted, so that the problems of uneven box thickness, light leakage and the like caused by different displacements of the first substrate and the second substrate when the liquid crystal display panel is bent for display are effectively solved.
