Problems solved by technology

[0004] The data line 13 of the existing array substrate may have phenomena such as burrs and delamination during its formation process, and the existence of these phenomena will cause a gap between the data line 13 and the source electrode 12 when a voltage is applied to the data line 13 . An uneven electric field will be generated, which may lead to large voltage differences on different pixel electrodes, which may cause spots (Mura) on the TFT LCD when reflected in the actual display effect

Embodiment 1

[0039] An embodiment of the present invention provides an array substrate, including a substrate, a data line formed on the substrate, a transparent conductive film covering the data line, at least one thin film transistor formed on the substrate, and a pixel electrode formed on the substrate . The thin film transistor includes a source electrode and a drain electrode, and the drain electrode is electrically connected to the data line. Optionally, the pixel electrode covers the source electrode and is electrically connected to the source electrode, the transparent conductive film directly covers the data line, and the above-mentioned substrate may be, but not limited to, a glass substrate.

[0040] It should be noted that, the transparent conductive film in the embodiment of the present invention may cover the data line, and may also partially cover the data line, which is not limited in the present invention.

[0041] like image 3 (other devices are not shown), which is a ...

Embodiment 2

[0048] The following is as image 3 and Figure 4 The manufacturing method of the shown array substrate is introduced in detail.

[0049] like Figure 5 As shown, it is a schematic flowchart of a manufacturing method of an array substrate provided in Embodiment 2 of the present invention, including the following steps:

[0050] Step 101 : forming a metal layer on the substrate 6 .

[0051] The substrate 6 may be, but not limited to, a glass substrate. Optionally, before the metal layer is formed on the substrate 6, the scan line and the active layer, and the insulating layer or passivation layer between the layers can be formed on the substrate 6, and then the metal layer is formed on the active layer. , of course, between the active layer and the metal layer, there may be a passivation layer or an insulating layer, which is not limited by the solution of the embodiment of the present invention.

[0052] This step 101 is the same as the implementation process of forming a...

Abstract

The invention discloses an array substrate, a display device and a manufacturing method of an array substrate. A data line is covered with a transparent conducting film, and burrs or delamination on the data line can be wrapped. When voltage is applied to the data line, voltage difference on different pixel electrodes can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an array substrate, a display device and a method for manufacturing the array substrate. Background technique [0002] With the maturity of thin film transistor (Thin Film Transistor, TFT) technology, TFT liquid crystal display (Liquid Crystal Display, LCD) has become a mainstream flat panel display. Among them, the structure of the array substrate in the liquid crystal display directly affects the display quality. [0003] like figure 1 Shown is a schematic diagram of an existing array substrate, wherein the pixel electrode 11 and the source electrode 12 are electrically connected. like figure 2 shown as figure 1 The cross-sectional view of the array substrate taken along BB'. [0004] The data lines 13 of the existing array substrate may have phenomena such as burrs and delamination during the formation process. The existence of these phenomena will cause th...
