The present invention aims at liquid crystal display panels with a thick insulating protective layer, that is, a JAS (organic insulating film) layer, and forms uneven contact hole areas around the effective display area of the panel by using the contact holes in adjacent arrangements arranged alternately. The "water-retaining wall" can not only prevent the diffusion of PI liquid in the cell process, but also be used for the electrical connection between the pixel electrode and the source-drain metal layer and the source-drain metal layer and the gate metal layer, so as to reduce the "water-retaining wall". The peripheral space occupied by the "wall" is conducive to realizing the narrow frame of the liquid crystal display panel.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1: a liquid crystal display panel with a JAS layer, including an array substrate 1, a JAS layer 2 is provided on the source-drain protection layer in the array substrate 1, and the JAS layer located outside the effective display area 4 of the panel 2 is provided with contact holes 3 formed after digging through the JAS layer 2. Multiple rows and columns of contact holes 3 are distributed around the effective display area 4 of the panel. The contact holes 3 in two adjacent rows are arranged alternately so that the outer rows The contact holes 3 are located on the upper or lower side of the gap between the two contact holes 3 in the inner row, and the contact holes 3 in two adjacent rows are arranged alternately so that the contact holes 3 in the outer row are located between the two contact holes in the inner row. 3 The left or right side of the gap position, and the diameter of the contact hole 3 is not smaller than the gap between two adjacent contact holes 3 in the same arrangement to prevent the continued diffusion of the PI liquid. If the above contact holes 3 do not use interlaced In the way of setting, the PI liquid may still spread along the flat JAS area, and in addition, the contact holes 3 located outside the effective display area 4 of the panel in the same direction must be arranged in at least two rows or columns to ensure that the contact holes 3 in adjacent arrangements are staggered set up. Among the above-mentioned contact holes 3, some contact holes 3 are dug through to the position of the source and drain metal layer of the array substrate 1 to facilitate the electrical connection between the pixel electrode and the source and drain metal layer, and some contact holes 3 are dug through to the position of the array substrate 1. The position of the gate metal layer on the substrate 1 is to facilitate the electrical connection between the source and drain metal layers and the gate metal layer. The liquid crystal display panel with the JAS layer described in FIG. 1 only shows the contact hole 3 area on the right side of the effective display area 4 of the panel, but actually the contact hole 3 area is provided around the effective display area 4 of the panel.

In the cell process of the liquid crystal display panel with the JAS layer of the present invention, the electrical connection between the pixel electrode and the source-drain metal layer and the electrical properties of the source-drain metal layer and the gate metal layer have been processed before the cell process. Therefore, in the diffusion process of the PI liquid, part of the diffused PI liquid first falls into the first row or column of contact holes 3, while part of the PI liquid that passes through the area of the first row or first column of contact holes 3 is It will fall into the contact hole 3 in the second row or column, so that the uneven contact hole 3 area can achieve the effect of "water retaining wall", and the PI liquid falling into the contact hole 3 will not damage the pixel electrode and the contact hole 3. The electrical connection between the source and drain metal layers and the electrical connection between the source and drain metal layers and the gate metal layer.

The present invention aims at a liquid crystal display panel with a thick insulating protective layer, that is, a JAS (organic insulating film) layer 2, and forms uneven contacts around the effective display area 4 of the panel by using the contact holes 3 in adjacent arrangements arranged alternately. The hole 3 area is the "water retaining wall", which can not only prevent the diffusion of PI liquid in the cell process, but also be used for the electrical connection between the pixel electrode and the source-drain metal layer and the source-drain metal layer and the gate metal layer, so as to Reducing the surrounding space occupied by the "retaining wall" is conducive to realizing the narrow frame of the liquid crystal display panel.
