Problems solved by technology
[0003] When the alignment fluid reaches the retaining wall, backflow accumulation will occur, resulting in an increase in the thickness of the alignment fluid, uneven display, or flow to the frame glue, causing the frame glue to fall off

The invention discloses an array substrate of a display panel, a manufacturing method and a display device. The array substrate comprises a substrate, a metal layer arranged on the substrate, an insulating layer arranged on the substrate for covering the metal layer, and a plurality of retaining walls arranged on the insulating layer of the array substrate, wherein the plurality of retaining wallsare arranged perpendicular to the coating direction of frame glue of the display panel, a height difference is formed between the plurality of retaining walls, and a part of the retaining walls are arranged at the positions, corresponding to the metal layer, of the insulating layers. According to a method for heightening the retaining walls by using the metal layer on the array substrate, a plurality of retaining walls which are gradually heightened are arranged, and an alignment liquid flows to the retaining walls and are blocked step by step; finally, an additional retaining wall and a groove are arranged, so that the alignment liquid is effectively prevented from flowing to the frame glue, and the frame glue is prevented from falling off; and then, the flow rate can be reduced every time when the alignment liquid flows through one retaining wall, so that the thickness increasing of the alignment liquid caused by backflow accumulation when the alignment liquid encounters the retaining walls due to the fact that the flow speed of the alignment liquid is relatively high can be avoided, so that the brightness of the display panel is more uniform.
Description
technical field [0001] The present application relates to the field of display technology, in particular to an array substrate of a display panel, a manufacturing method and a display device. Background technique [0002] In the field of Thin Film Transistor Liquid Crystal Display (TFT-LCD), a liquid crystal display panel is mainly composed of a color filter substrate, an array substrate, and a liquid crystal layer filled between the two substrates. Alignment films are provided on the two substrates, and the liquid crystals can be aligned and arranged along the grooves on the alignment films, and the liquid crystals are controlled by an electric field to form a display screen. The two substrates are fixed and installed by sealing glue. Usually, a layer of alignment liquid (PI) is coated on the substrate to form a pre-tilt angle to facilitate liquid crystals to have a fixed inversion during display. Alignment liquid is a kind of fluid chemical liquid, which will diffuse and...
