Provided is a pixel structure, an array substrate, and a liquid crystal display panel. In the pixel structure, a sub-pixel region is horizontally arranged, and a data line passes through the sub-pixel region in a vertical direction, so that parasitic capacitance between the data line and a pixel electrode is effectively reduced, and a phenomenon of vertical crosstalk is eliminated. A distance between the data line and common electrode is configured to be greater than a predetermined distance, thereby avoiding arrangement of an additional black matrix. This improves aperture ratio and transmittance of the panel, and optimizes display effects.
