An array substrate and a liquid crystal display panel are provided, wherein the array substrate includes a display area and a non-display area, and a length of one end of via-holes close to the display area is not greater than 12.5 microns. By reducing a length of one end of the via-holes positioned at a boundary position between the display area and the non-display area close to the display area, a flow of polyimide fluid is guided and enables an edge of a polyimide film to cover an area where the via-holes are located.
