The disclosure discloses an array substrate, a liquid crystal display panel, and a display device, and the array substrate includes: a base substrate; a plurality of pixel units with pixel electrodes on the base substrate; where each of at least a part of the plurality of pixel units is provided with at least one recess, and a pixel electrode in each of the at least a part of the plurality of pixel units covers the at least one recess; where an orthographic projection of an opening of each recess onto the base substrate overlaps with an orthographic projection of a bottom thereof onto the base substrate, and an area of the orthographic projection of the opening of the recess onto the base substrate is greater than an area of the orthographic projection of the bottom thereof onto the base substrate.
