Problems solved by technology

[0003] It can be seen that the above-mentioned production process for forming a liquid crystal display panel is relatively cumbersome, and polarizers need to be pasted separately after the box is aligned, which is not conducive to improving production efficiency; It will increase the production cost; finally, the polarizer attached to the outside of the display panel has a certain thickness, which will limit the overall thickness of the formed liquid crystal display panel, which is not conducive to the development of light and thin devices

Embodiment 1

[0039] In this example, if Figure 2a and Figure 2b As shown, the pixel electrode and the wire grid polarizing film are multiplexed in the array substrate. Specifically, the wire grid polarizing film 004 is multiplexed as a pixel electrode in each pixel area, and is electrically connected to the drain 005 of the thin film transistor disposed at the intersection of the data line 002 and the gate line 003. The drain 005 is generally connected to the data line 002 Same level settings.

[0040] Specifically, when the wire grid polarizing film 004 is arranged on the same layer as the data line 002, as Figure 2aAs shown, at this time, since the wire grid polarizing film 004 serving as the pixel electrode is fabricated on the same layer as the drain 005 of the thin film transistor, the two can be directly electrically connected. When the wire grid polarizing film 004 is set on the same layer as the grid line 003, as Figure 2b As shown, at this time, the wire grid polarizing fi...

Embodiment 2

[0045] In this example, if Figure 3a and Figure 3b As shown, the pixel electrodes and common electrodes in the array substrate in the IPS mode are multiplexed with the wire grid polarizing film. Specifically, in the structure of the array substrate in the IPS mode, the pixel electrode and the common electrode in each pixel unit are arranged on the same layer in an interleaved finger structure. Therefore, in each pixel area, the wire grid polarizing film 004 is multiplexed as the pixel electrode and the common electrode of the interpolation structure; wherein, the wire grid polarizing film 004 multiplexed as the pixel electrode and the wire grid polarizing film 004 disposed at the intersection of the data line 002 and the gate line 003 The drain 005 of the TFT is electrically connected, and the drain 005 and the data line 002 are arranged on the same layer.

[0046] Specifically, when the wire grid polarizing film 004 is arranged on the same layer as the data line 002, as ...

Embodiment 3

[0050] In this example, if Figure 4 As shown, the pixel electrode and the wire grid polarizing film are multiplexed in the array substrate. Specifically, the wire grid polarizing film 004 and the grid lines 003 can be provided on the same layer, and the wire grid polarizing film 004 can be multiplexed as a common electrode in each pixel area.

[0051] In actual implementation, when making Figure 4 In the case of the ADS type array substrate with the structure shown, the wire grid polarizing film 004 used as the common electrode is set to be fabricated simultaneously with the grid line 003 and the grid 006, so that the existing common electrode formed separately on the pixel electrode can be omitted. Therefore, compared with the existing array substrate manufacturing process, the number of mask plates used and the manufacturing process can be saved.

Abstract

The invention discloses an array substrate, a liquid crystal display panel and a display device. Wire grating polarizing films manufactured in each pixel region in the array substrate are adopted for replacing existing polaroids attached to the outer side of the array substrate, and are of a grating structure with the grating space being less than half of the minimum wavelength in visible lights, so an effect of changing passing natural lights into linearly polarized lights is achieved. On the premise of ensuring that the liquid crystal display panel can display normally, the wire grating polarizing films with effects of the polaroids are formed in the process of manufacturing the array substrate, so that a working process of independently laminating the polaroids after box aligning box can be omitted, the production efficiency, the manufacturing cost is saved, and the whole thickness of the display panel can be favorably thinned.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to an array substrate, a liquid crystal display panel and a display device. Background technique [0002] A liquid crystal display panel is mainly composed of an array substrate, an opposite substrate, and liquid crystal molecules located between the array substrate and the opposite substrate. In the production process, after the film layers on the array substrate and the opposite substrate are fabricated respectively, the array substrate and the opposite substrate are subjected to cell alignment, and then polarizers need to be pasted on the upper and lower surfaces of the liquid crystal display panel. , and finally install a backlight module on one side of the array substrate to form the final display panel. [0003] It can be seen that the above-mentioned production process for forming a liquid crystal display panel is relatively cumbersome, and polarizers need to be ...
