Abstract

The invention provides an array substrate and a manufacturing method thereof, a liquid crystal display panel and a display device. The array substrate comprises a substrate base plate; a thin film transistor array layer arranged on one surface of the substrate base plate; an organic layer arranged on the partial surface, far away from the substrate base plate, of the thin film transistor array layer, wherein at least one air hole is formed in the organic layer; and a passivation layer which is arranged on the surface, far away from the substrate base plate, of the organic layer and covers the inner wall of the air hole. Gas in the organic layer of the array substrate can be well discharged in the manufacturing process, stress in the organic layer can also be well released, then the surface of the array substrate is not prone to generating bumps or cracking, the shading effect of the black matrix in the array substrate is good, and color crossing of the display device is not prone to occurring; and the array substrate is good in bending and resistance and particularly suitable for a flexible display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an array substrate and a manufacturing method thereof, a liquid crystal display panel and a display device. Background technique [0002] In the related art, after a long period of use of the liquid crystal display panel, the surface of the array substrate therein tends to be bulged or cracked, resulting in failure of the display device. [0003] Therefore, the related technology of the existing liquid crystal display panel still needs to be improved. Contents of the invention [0004] The present invention is accomplished based on the following findings of the inventors: [0005] After a lot of in-depth investigation and experimental verification of the invention, it is found that the reason why the surface of the array substrate in the related art is prone to bulging or cracking is that: in the process of manufacturing the array substrate, refer to Figure 1a , aft...
