Liquid crystal display panel and preparation method thereof

Abstract

The invention provides a liquid crystal display panel. The liquid crystal display panel comprises a colored film substrate, an array substrate and a redundant isolation part, wherein the array substrate and the colored film substrate are arranged oppositely; the array substrate comprises a frame adhesive coating region; the frame adhesive coating region is provided with a first metal cable, an insulating layer located above the first metal cable and a second metal cable located above the insulating layer; a through hole is formed in the insulating layer in the frame adhesive coating region; the second metal cable is connected with the first metal cable through the through hole; the redundant isolation part is formed on the frame adhesive coating region and correspondingly covers the through hole. The liquid crystal display panel provided by the invention has the beneficial effects that the an isolation layer is arranged between the surface of the frame adhesive coating region and the through hole so as to protect the through hole from being corroded by water vapor.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a preparation method thereof. Background technique [0002] In recent years, liquid crystal display panels generally adopt the GOA design (Gate driver on Array, array substrate line drive technology), that is, the combination of various TFT (thin film transistor) lines on the array substrate realizes the scanning line function, replacing the gate driver chip, in order to realize The purpose of reducing costs. The functional signal lines are connected to the GOA lines at all levels through many via holes to control the transmission of scanning signals. [0003] In narrow bezel products, it is often necessary to design the frame glue on the functional signal line. However, in a high-temperature and high-humidity operating environment, due to the absorption of water vapor by materials such as alignment fluid and frame glue, the via...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a liquid crystal display panel, which can protect the via holes located in the frame glue coating area from short circuit caused by water vapor corrosion, so as to solve the problem of the existing liquid crystal display panel, because the frame glue coating area located at the edge of the array substrate is provided with Frame glue, the frame glue covers part of the vias used to realize the connection between the functional signal line and the GOA line. The frame glue absorbs water vapor and easily causes the via holes to be corroded, which in turn affects the technical problems of the display.
