Abstract
An array substrate, a manufacturing method thereof and a liquid crystal display panel are provided. The array substrate comprises a source-drain layer stacked, a pixel electrode layer and an interval layer, comprising a via hole structure. The pixel electrode layer is electrically connected to the source-drain layer through the via hole structure, comprising a via hole and a plurality of drainage grooves provided at intervals on an edge of the via hole. The pixel electrode layer forms a groove corresponding to the via hole, and the pixel electrode layer forms a sub-drainage groove corresponding to each drainage groove. When the alignment layer is disposed on the pixel electrode, an alignment liquid for forming an alignment layer flow into the groove through a sub-drainage groove, so that the groove can also cover an alignment film and ensure a normal display of the liquid crystal display panel formed by the array substrate.
