Embodiment 1

[0027] As mentioned in the background art, the array substrate using the comb electrode structure in the prior art has the problem of low light transmittance. The inventors of the present invention have found through research that one of the reasons for the above-mentioned problem is: as figure 1 and 2 As shown, since the pixel electrode 1 and the common electrode 2 are formed in the same patterning process in the prior art, the electrode material between the pixel electrode 1 and the common electrode 2 is etched to form the pattern of the pixel electrode 1 and the common electrode 2 In the process, limited by the process capability, there will be electrode material residue between the pixel electrode 1 and the common electrode 2. end, ie figure 1 The X shown in is especially serious. If the gap d between the pixel electrode 1 and the common electrode 2 at X is too small, there will be more electrode material remaining between the two at X, causing the two to be unable to b...

Embodiment 2

[0048] This embodiment provides an array substrate, such as Figure 6 As shown, the array substrate includes: a base substrate 3, a first electrode 6 disposed on the base substrate 3, a passivation layer 5 covering the first electrode 6 and roughly the same shape as the first electrode 6, disposed on the substrate The second electrode 8 on the base substrate 3 . Wherein, an electric field can be formed between the first electrode 6 and the second electrode 8 , and the electric field may include a horizontal electric field parallel to the base substrate 3 for driving liquid crystal molecules to deflect.

[0049] In the above array substrate, since the passivation layer 5 and the first electrode 6 have approximately the same shape, the passivation layer 5 and the first electrode 6 can be formed in the same patterning process, and since the passivation layer 5 covers the first Therefore, the first electrode 6 and the second electrode 8 can be formed in different patterning proce...

Embodiment 3

[0059] This embodiment provides a display device, which includes the array substrate as described in the second embodiment. Since the gap between the first electrode and the second electrode in the array substrate described in the second embodiment can be set smaller, the light transmittance is higher, and the signal crosstalk between the first electrode and the second electrode is acceptable. Therefore, the display device including the array substrate also has the advantages of high light transmittance and signal crosstalk within an acceptable range.

[0060] It should be noted that the display device provided in this embodiment is preferably a liquid crystal display device, specifically any product with a display function such as a liquid crystal panel, a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a navigator, etc. or parts.

Abstract

The invention provides an array substrate, a manufacturing method thereof, and a display device, which relate to the field of display technology and can solve the problem of low light transmittance of the array substrate adopting a comb-shaped electrode structure. The method for manufacturing the array substrate includes: sequentially forming a first conductive film and a passivation layer film on a base substrate; using a patterning process to remove the passivation layer film and the first conductive film except for the region where the first electrode is to be formed , form the pattern of the passivation layer and the pattern of the first electrode; form the second conductive film on the substrate with the pattern of the passivation layer and the pattern of the first electrode; adopt a patterning process to remove the pattern to be formed The second conductive film outside the second electrode area forms the pattern of the second electrode. The above method for manufacturing an array substrate is used for manufacturing an array substrate.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] Liquid crystal display device is currently the most mainstream display device in the field of display technology. According to the different arrangement of liquid crystal molecules, liquid crystal display device can be divided into TN (Twisted Nematic, twisted nematic) type, IPS (In-Plane Switching, in-plane switching ) type, VA (Vertical Alignment, vertical orientation) type and other types. Among them, the IPS type liquid crystal display device has the advantages of wide viewing angle, fast response speed, accurate color reproduction, etc., and has received extensive attention in the field. [0003] The array substrate of the IPS liquid crystal display device has various structures, and the manufacturing process of the array substrate of one structure requires four ...
