Problems solved by technology
[0005] see figure 2 As shown, when the liquid crystal display panel is squeezed or impacted (that is, transverse shear stress or longitudinal shear stress), the columnar spacers 31 and 32 will automatically move to a lower position, and the dislocation of the two parts of the spacers cannot be recovered. The original position leads to misalignment between the array substrate 1 and the color filter substrate 2, which in turn causes display defects such as light leakage and touch mura

Embodiment Construction
[0023] see image 3 and Figure 4 As shown, the liquid crystal display panel 100 includes a color filter substrate 10, an array substrate 20 disposed opposite to the color filter substrate 10, a liquid crystal filled between the color filter substrate 10 and the array substrate 20, and a liquid crystal disposed between the color filter substrate 10 and the array substrate 20. A plurality of main spacers 31 and a plurality of sub-spacers 32 between the array substrates 20 are used to maintain the distance between the array substrate 10 and the color filter substrate 10 after box alignment.
[0024] In this embodiment, the main spacer portion 31 and the sub-spacer portion 32 are disposed on the color filter substrate 10 .
[0025] The array substrate 20 is provided with at least one wedge-shaped structure corresponding to the sub-spacer portion 32. When the liquid crystal display panel 100 is subjected to transverse shear stress or longitudinal shear stress, the wedge-shaped st...

The invention provides a liquid crystal display panel. The liquid crystal display panel comprises a colored film substrate, an array substrate, a plurality of main partitioning cushion parts and a plurality of auxiliary partitioning cushion parts, wherein the array substrate is opposite to the colored film substrate; the plurality of main partitioning cushion parts and the plurality of auxiliary partitioning cushion parts are arranged on the colored film substrate; the array substrate is provided with at least one wedge-shaped mechanism corresponding to the auxiliary partitioning cushion parts; the wedge-shaped mechanism is provided with an inclined plane corresponding to the bottom part of the auxiliary partitioning cushion part. The liquid crystal display panel provided by the invention has the advantages that by the wedge-shaped structure, when the liquid crystal display panel is stressed by horizontal shearing stress or longitudinal shearing stress, the wedge-shaped structure can give out an opposite restoring force to the auxiliary partitioning cushion parts or the main partitioning cushion parts, so that the staggering is avoided and further the phenomenon of light leakage is avoided.
Description
technical field [0001] The invention relates to a liquid crystal display device. [0002] technical background [0003] see figure 1 As shown, the liquid crystal display panel includes a color filter (Color Filter) substrate 1 , an array (Array) substrate 2 , and liquid crystals filled between the color filter substrate and the array substrate. The thickness of the liquid crystal layer has an important influence on the structural parameters and display quality of the liquid crystal display panel. [0004] In order to control the uniformity of the thickness of the liquid crystal layer, spacers are arranged between the two substrates in the prior art. A spacer widely used in current products is a columnar spacer (Photo Spacer, hereinafter referred to as PS). That is, at a distance of one or several sub-pixels, columnar spacers are evenly arranged, and the columnar spacers are used to maintain the distance between the array substrate and the color filter substrate after box a...
