The disclosure provides an array substrate, a manufacturing method thereof, and a liquid crystal display (LCD) panel. The array substrate includes a substrate, a driving circuit layer, a pixel electrode layer, and an astigmatism layer, which are stacked. The pixel electrode layer includes a plurality of pixel electrodes which are independent from each other. The astigmatism layer includes a plurality of astigmatism components which are connected to each other and correspond to the pixel electrodes. An area of a light-emitting surface of the astigmatism components away from the pixel electrodes is greater than an area of an electrode surface of the pixel electrodes away from the substrate. The disclosure improves viewing angles.
