Embodiment 1

[0054] Such as Figure 3a As shown, the array substrate may further include a plurality of third connection portions 130, arranged between two adjacent pixel units 01 along the second direction, for electrically connecting the common electrodes 10 of the two adjacent pixel units 01 .

[0055] Specifically, the above-mentioned third connecting portion 130 may be made of a transparent conductive material. When the third connection part 130 is made of a transparent conductive material, a via hole (not shown) can be formed on the surface of the pixel electrode 11 at a position corresponding to the third connection part 130, and then a third connection made of a transparent conductive material can be made. The part 130 electrically connects the common electrodes 10 of two adjacent pixel units 01 through the above-mentioned via holes. However, the pixel electrode 11 is also made of transparent conductive material. Therefore, it is also necessary to form an insulating layer betwee...

Embodiment 2

[0064] Such as Figure 4aAs shown, on the basis of Embodiment 1, the array substrate may further include a plurality of fourth connecting parts 140, which are arranged on the peripheral common electrode line 02 and the pixels on the side close to the peripheral common electrode line 02 along the second direction. Between the common electrodes 10 of the unit 01 is used to electrically connect the peripheral common electrode line 02 to the common electrode 10 of the above-mentioned pixel unit 01 .

[0065] Like the third connecting portion 130 in the first embodiment, the fourth connecting portion 140 may also be made of transparent conductive material.

[0066] Alternatively, in order to improve the electrical conductivity of the fourth connecting portion 140, the fourth connecting portion 140 may also be made of a metal material.

[0067] Preferably, in the case where the array substrate includes data lines 101, such as Figure 4b ( Figure 4a sectional view along BB').

Embodiment 3

[0091] Such as Figure 7 shown, including:

[0092] S201, such as Figure 8a As shown, a common electrode layer 04 is formed on a base substrate 03 .

[0093] Specifically, the above-mentioned common electrode layer 04 may be made of a transparent conductive material, such as ITO. The common electrode layer 04 may be deposited on the surface of the base substrate 03 by using a magnetron sputtering method.

[0094] S202 , forming a gate metal layer 05 on the surface of the common electrode layer 04 .

[0095] Specifically, the aforementioned gate metal layer 05 may be formed on the surface of the common electrode layer 04 by coating or magnetron sputtering.

[0096] S203, such as Figure 8b shown (where, Figure 8b —8d is edge Figure 3a The cross-sectional view of CC' is described by taking the second connection part 120 as an example, and the manufacturing process of the first connection part 110 can be obtained in the same way), and a layer of photoresist is coated on...

Abstract

The invention provides an array substrate and a preparation method thereof as well as a display device, relating to the field of display technologies and solving the problem of capability of reducing an aperture ratio of the display device through a public electrode wire. The array substrate comprises a peripheral public electrode wire used for providing public voltage, a plurality of pixel units, a plurality of first connecting parts and second connecting parts, wherein the first connecting parts are arranged between the peripheral public electrode wire and a public electrode close to the pixel unit on one side of the peripheral public electrode wire along a first direction, and the peripheral public electrode wire is electrically connected to the public electrode. The second connecting parts are arranged between the public electrodes of every two adjacent pixel units along the first direction, so that the two adjacent public electrodes are electrically connected.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor Liquid Crystal Display, Thin Film Transistor Liquid Crystal Display), as a flat panel display device, has become more and more popular due to its small size, low power consumption, no radiation and relatively low production cost. It is widely used in the field of high-performance display. [0003] TFT-LCD consists of an array substrate and a color filter substrate. A liquid crystal layer is provided between the array substrate and the color filter substrate, and an electric field is formed in the liquid crystal layer by applying voltages to the pixel electrodes provided on the array substrate and the common electrodes provided on the color filter substrate or the array substrate respectively. Then, the transmittance of light passing throug...
