Problems solved by technology

[0003] During daily use or during the back pressure test of the liquid crystal panel, after the liquid crystal panel is squeezed by external force, the array substrate 2 and the color filter substrate 1 in the liquid crystal panel will shift, and the main support column 12 and the auxiliary support column 13 will also shift along with it, and the contact surface between the main support pillar 12 and the array substrate 2 is not fixed, and the main support pillar 12 will scratch the array alignment film layer 82 of the array substrate 2, thereby causing light leakage at the scratched place ,like figure 2 Shown is a plan view of an array substrate whose array alignment film layer is scratched and causes light leakage. The edge of the pixel area 15 around the corresponding position 16 of the supporting pillars will cause light leakage at the bad position 17 caused by the offset of the main supporting pillars 12.
[0004] After analyzing the bad position, one of the reasons why the support pillars scratch the array alignment film layer is that the adhesion between the array alignment film layer and the insulating layer is insufficient, which makes it easy for the support pillars to rub the array alignment film layer during the shifting process, scratching array alignment layer

Embodiment 1

[0029] image 3 It is a schematic structural diagram of a liquid crystal display panel of the present invention, a liquid crystal display panel, comprising: an array substrate 2 and a color filter substrate 1 disposed opposite to each other, and a liquid crystal layer 18 sandwiched between the array substrate 2 and the color filter substrate 1 .

[0030] Among them, the array substrate 2 includes a glass substrate 3, a TFT layer 4, a common electrode 5, an insulating layer 6, a pixel electrode 7, and an array alignment film layer 82 arranged in sequence, and the color filter substrate 1 includes a glass substrate 3 and a black matrix 10 arranged in sequence. And the color layer 11, the protective layer 9, the supporting pillars and the color filter alignment film layer 81.

[0031] The liquid crystal display panel of the present invention is an FFS liquid crystal display panel, and a fringe electric field is generated between the common electrode 5 and the pixel electrode 7 to...

Embodiment 2

[0038] Embodiment 1 is improved, such as Figure 4 As shown, the solidified metal layer 14 of the array substrate 2 is not only under the main support pillars 12, but also under the auxiliary support pillars 13. The solidified metal layer 14 is also provided under the auxiliary support pillars 13. Compared with the first embodiment, this embodiment can make the liquid crystal display panel More pressure resistance, when the auxiliary support pillars 13 are pressed into contact with the array alignment film layer 82 of the array substrate 2, there will also be no scratches on the array alignment film layer 82, which improves the pressure resistance effect of the liquid crystal display panel.

[0039] It should be noted that the cured metal layer 14 can be as Figure 5 circular as shown, such as Figure 6 The ellipse shown, such as Figure 7 The square shown, such as Figure 8 As shown in the hexagon, and other polygons, as long as the cross-sectional area of ​​the solidified...

Abstract

The invention discloses a liquid crystal display panel, comprising: an array substrate and a color filter substrate arranged oppositely, and a liquid crystal layer sandwiched between the array substrate and the color filter substrate, the array substrate includes an array alignment film layer, and the color filter The substrate includes a black matrix, a color layer, and support columns. The array substrate also includes a solidified metal layer at the corresponding position of the support column. A cured metal layer is arranged under the alignment film layer, and the cured metal layer increases the adhesion between the array alignment film layer and the cured metal layer, as well as the cured metal layer and the insulating layer, and solves the scratching of the array alignment film layer caused by the support column offset rubbing the array alignment film layer. The problem of damage can be improved to improve the yield rate of LCD panels.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal display panel capable of preventing support columns from scratching an alignment film. Background technique [0002] Liquid crystal display panels have the advantages of small size, low power consumption, and no radiation. They have developed rapidly in recent years and currently play a leading role in the flat panel display market. figure 1 As shown, it includes an array substrate 2 and a color filter substrate 1 arranged oppositely and a liquid crystal layer 18 sandwiched between the array substrate 2 and the color filter substrate 1. The array substrate 2 and the color filter substrate 1 pass through the main support column 12 and the auxiliary support column. separated by 13, the color filter substrate 1 is sequentially composed of a glass substrate 3, a black matrix 10, a color layer 11, a protective layer 9, and a color filter alignment film...
