The invention provides an array substrate, a fabrication method thereof and a liquid crystal display panel comprising the array substrate. The array substrate comprises a substrate, a plurality of pixel electrodes, a plurality of scanning lines, a plurality of data lines and scanning line connection lines; the substrate is divided into a display area and a frame area, and the display area is surrounded by the frame area; the pixel electrodes are arranged in the form of an array in the display area; the scanning lines are positioned among the pixel electrodes; the data lines are positioned among the pixel electrodes, and are insulatively intersected with the scanning lines; and the scanning line connection lines are positioned in the display area, are in parallel with the data lines, and are correspondingly and electrically connected with the scanning lines to transmit the signals of a scanning drive circuit to the corresponding scanning lines. The area of the frame area of the array substrate and the liquid crystal display panel is reduced, consequently, the frame of a liquid crystal display is narrowed, and the utilization rate of the substrate is increased.
