Problems solved by technology

[0004] However, during the process of injecting the liquid crystal material into the substrate group, foreign matter may flow into the substrate group along with the liquid crystal material.
When the foreign matter is conductive, a short circuit may occur inside the LCD panel
In particular, when the LCD panel is pressed, there is a higher probability of a short circuit inside the LCD panel
Therefore, the inflow of foreign matter will lead to poor quality of the liquid crystal display panel

Abstract

The invention relates to a substrate group and a liquid crystal display (LCD) panel. The substrate group comprises a first substrate, a second substrate, a frame sealant and a barrier structure, wherein the first substrate is provided with an active region; the frame sealant is configured between the first substrate and the second substrate, the first substrate and the second substrate are assembled through the frame sealant and are spaced from each other at a distance of a bug hole so as to define a space, and the frame sealant is provided with a filling opening; and the barrier structure is configured on the first substrate and is positioned outside the active region, the distance from the barrier structure to the second substrate is smaller than that of the bug hole, the barrier structure divides the space into a first region and a second region, the filling opening is only positioned in the first region, and the active region is only positioned in the second region. The substrate group can prevent foreign matters from flowing into the active region of the substrate so as to improve the quality of the LCD panel.

Description

technical field [0001] The invention relates to a substrate group and a liquid crystal display panel, in particular to a substrate group and a liquid crystal display panel with injection openings in the sealant. Background technique [0002] Generally speaking, a liquid crystal display panel is composed of an active device array substrate, a liquid crystal layer and a color filter array substrate. The manufacturing method of the liquid crystal display panel is to combine the two substrates into a substrate group by coating a layer of frame glue between the thin film transistor array substrate and the color filter substrate. Next, the liquid crystal layer is injected into the substrate group, and then the sealant is completely sealed. [0003] A common way to inject the liquid crystal layer between the substrate groups is the vacuum suction injection method. The vacuum suction injection method is mainly to place the substrate group and the liquid crystal dish filled with li...
