Array substrate, repair method for broken lines of array substrate and display device

Abstract

The invention relates to liquid crystal display devices, in particular to an array substrate, a repair method for broken lines of the array substrate and a display device. The array substrate comprises a common electrode, pixel electrodes, thin film transistors, grid lines and data lines, wherein the grid lines and the data lines are arranged in a crossed mode to form a plurality of pixel areas which are arranged in a matrix mode, a plurality of patterns which are of a strip-shaped and hole-shaped structure are respectively arranged the common electrode above each pixel area, the grid lines, the data lines and the common electrode are manufactured on different layers and mutually overlap with one another in a partial mode, and a pattern which is of a first hole-shaped structure is arranged at the position, corresponding to the crossed position of each grid line and each date line, of the common electrode. Due to the design of the patterns of a common electrode layer, the broken lines of the data lines and the grid lines on the array substrate can be conveniently and rapidly repaired, limitation of the number of the broken lines is overcome by repair of the broken lines of the data lines, and product yield of the array substrate is effectively improved.

Description

Technical field [0001] The present invention relates to a liquid crystal display device, and in particular to an array substrate, a method for repairing broken wires of the array substrate, and a display device. Background technique [0002] In the manufacturing process of liquid crystal display panels, repairing broken wires is an important means to improve yield. In the prior art, a structure of laying data repair lines around the liquid crystal display panel is generally adopted to facilitate repair of broken grid lines. [0003] ADS-type liquid crystal panel (Advanced-Super Dimensional Switching; Advanced Super Dimensional Switching Technology) forms a multi-dimensional electric field through the parallel electric field generated by the edge of the pixel electrode or the common electrode in the same plane and the longitudinal electric field generated between the pixel electrode and the common electrode. All the aligned liquid crystal molecules between the pixel electrode or th...

Problems solved by technology

However, if this method is used to repair the array substrate, due to the limited number of disconnected repair lines 9, there is a limit to the number of data lines to be repaired, and generally two disconnected data lines can be repaired at most.

Moreover, there is no mature method for repairing broken wires of grid lines at present.

If the disconnection of the array substrate cannot be effectively repaired, it will affect the yield of liquid crystal display products
