[0032] This embodiment provides an array substrate. figure 1 It is a top view of the array substrate structure of this embodiment. figure 2 It is a cross-sectional view along A-A' of the array substrate structure of the present invention. figure 1 It exemplarily shows a pixel area limited by intersecting gate lines 1 and data lines 21, in which there are pixel electrodes 9 and common electrode lines 8, wherein the data lines 21 are used to provide the corresponding pixel electrodes 9 transmits data signals; the gate lines 1 are used to transmit scan signals to the corresponding pixel electrodes 9; there are a plurality of such pixel regions (not shown) on the array substrate. There are connecting lines between the common electrode lines 8 and the data lines 21 , and the connecting lines include a first connecting line 6 and a second connecting line 7 . Wherein, the first connection line 6 is specifically a strip structure arranged between the gate line 1 and the common elec...

specific Embodiment 2

[0036] This embodiment provides a method for manufacturing the array substrate in the first embodiment. Figure 3-10 The cross-sectional views of the array substrate structures manufactured by each process. like image 3 As shown, firstly, a first metal layer 12 is deposited on the substrate 10 by means of reactive sputtering, chemical vapor deposition, etc., and the material of the first metal layer 12 is aluminum, titanium, molybdenum and the like. The first metal layer 12 is patterned, and the patterning process includes coating photoresist, exposure, development, wet etching or dry etching the first metal layer, stripping photoresist and other conventional processes. The first metal layer 12 is patterned to obtain the gate and common electrode line 8 of the thin film transistor, such as Figure 4 shown.

[0037] Next, the gate insulating film 2 completely covering the gate and the common electrode line 8 is formed on the substrate 10, such as Figure 5 As shown, the ma...

Abstract

The invention discloses an array substrate and a manufacturing method thereof. The array substrate comprises a substrate, a plurality of pixel areas on the substrate; pixel electrodes arranged in the pixel areas; The electrode transmits a data signal; the gate line is used to transmit a scan signal to the corresponding pixel electrode; the common electrode line, the common electrode line and the pixel electrode form a storage capacitor; the thin film transistor, the gate of the thin film transistor and the The gate line is connected, the source in the thin film transistor is connected to the data line; the connection line is arranged between the data line and the common electrode, and the data line is connected to the common electrode through the connection line. The electrode wires are connected together. The array substrate of the present invention eliminates electrostatic damage in pixels through the connecting lines between the data lines and the common electrode lines, and does not increase the complexity of the process.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display devices, in particular to an array substrate for eliminating electrostatic damage and a manufacturing method thereof. Background technique [0002] At present, liquid crystal displays have gradually become the mainstream of display equipment development due to their advantages of high definition, true color video display, light and thin appearance, low power consumption, and no radiation. A liquid crystal display generally includes a liquid crystal display panel for displaying pictures and a circuit part for supplying signals to the liquid crystal display panel. The liquid crystal display panel usually includes a color filter substrate and an array substrate, which are bonded to each other by a frame glue and separated by a gap, and liquid crystal material is injected into the gap between the color filter substrate and the array substrate. [0003] A plurality of gate lines...
