Array substrate, method for manufacturing same, display panel and display device

The invention discloses an array substrate, a method for manufacturing the same, a display panel and a display device. The array substrate comprises a gate insulation layer, a first passivation layer, an organic film layer and a second passivation layer. The gate insulation layer, the first passivation layer, the organic film layer and the second passivation layer are arranged on a substrate, the second passivation layer is provided with hollow-out regions, and the hollow-out regions correspond to regions, and frame sealing adhesive can cling to the regions. The array substrate, the method, the display panel and the display device have the advantages that external water vapor can be prevented from flowing into the array substrate, and accordingly the reliability of the display panel can be improved.
