Liquid crystal display panel and method of manufacturing and restoring the same

Abstract

The invention provides a liquid crystal display panel and a method of manufacturing and restoring the same. The liquid crystal display panel comprises vertically and horizontally staggered grids and data lines, a horizontal common electrode line, a grating insulating layer on the grating, a metal-oxide semiconductor layer on the grating insulating layer, an etching barrier layer on the metal-oxide semiconductor layer, a source electrode, a drain electrode, a JAS layer, a second metal connecting line which is connected with a longitudinal common electrode, and a pixel electrode, wherein the horizontal common electrode line and the grading are formed at the same time; the source electrode and the drain electrode are electrically connected with the metal-oxide semiconductor layer; and the JAS layer covers the source electrode, the drain electrode, the second metal connecting line and a data line. The liquid crystal display panel and the method of manufacturing and restoring the same can solve the problem that a current pixel is small in the aperture ratio and is distorted, thus reducing the time of signal transmission, avoiding distortion caused by signal delay, and at the same time can reduce the line layout surrounding a panel and save the space of the panel and the production cost.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and its manufacturing and repairing methods. Background technique [0002] Existing liquid crystal display panels that use amorphous silicon as the semiconductor layer, such as figure 1 As shown, the design of the amorphous silicon liquid crystal display panel mainly considers the bridging of the upper and lower pixels. The manufacturing steps of the amorphous silicon liquid crystal display panel are: the first step: the pattern of the gate 1 formed by the first metal, The pattern of the horizontal common electrode 2 parallel to the gate 1 and the vertical and horizontal common electrode 3 parallel to the predetermined data line 5; the second step: forming a gate insulating layer (not shown) covering the first metal layer; the third step: Forming a semiconductor layer 4 made of amorphous silicon; the fourth step: forming the source a...

AI Technical Summary

Problems solved by technology

[0003] Since the vertical common electrode 3 is formed before the JAS hole 6, it is inevitable that there is a certain gap 8 between the vertical common electrode 3 and the pixel electrode 7, which seriously limits the aperture ratio of the pixel electrode; in addition, the impedance of the JAS is relatively large, making the display screen very easy to distort

[0004] The repair methods of existing liquid crystal display panels mostly use in-plane repair, which not only occupies a lot of space on the liquid crystal display panel, but also easily leads to signal distortion problems
