Problems solved by technology
In the process of etching the through hole, the size of the through hole is difficult to control, which may cause the distance between the pixel electrode and the common electrode to be relatively close, and a short circuit occurs in a certain place, so that the pixel is always in a dark state, causing the display screen color anomaly in

The invention provides a manufacturing method of a liquid crystal displayer array substrate. The manufacturing method comprises the steps that a plurality of grids, a plurality of grid lines and a plurality of public electrode lines are formed on the surface of the substrate, a grid insulation layer is formed to cover the substrate, the grids and the public electrode lines, a plurality of pixel electrodes are formed on the grid insulation layer, a passivation layer is formed to cover the whole substrate, a transparent conductive layer sediments on the passivation layer and is etched to form a hole which is at least overlapped with part of the public electrode lines, the passivation layer and the insulation layer are patterned so that a through hole can be formed below the hole, the through hole penetrates through the passivation layer and the grid insulation layer, part of the public electrode lines are exposed, the transparent conductive layer is removed, and a public electrode is formed on the passivation layer to cover the inner surface of the through hole and is connected with the public electrode lines.
Description
technical field [0001] The invention relates to a liquid crystal display, in particular to a method for manufacturing an array substrate of a liquid crystal display. Background technique [0002] As a display method of liquid crystal displays, Twisted Nematic (TN) method has been widely used in the past, but this method has limitations on the viewing angle in terms of display principles. [0003] As a method for solving this problem, a transverse electric field method is known, for example, an in-plane switching (In Plane Switching, IPS) method and a fringe field switching (Fringe Field Switching, FFS) method. In the transverse electric field method, a pixel electrode and a common electrode are formed on the array substrate, and a voltage is applied between the pixel electrode and the common electrode to generate an electric field substantially parallel to the array substrate, and the horizontal electric field is substantially parallel to the array substrate. drive the liqu...
