    Abstract: Embodiments of the invention disclose a liquid crystal alignment method, a pixel structure, a display panel, and a display device, which pertain to the field of display technologies. The liquid crystal alignment method comprises: forming, on a first substrate, at least two spaced apart annular electrode lines; forming an alignment film on the first substrate on which the at least two spaced apart annular electrode lines are formed; disposing a convex lens on the first substrate on which the alignment film is formed, the center point of the convex surface of the convex lens being in contact with the alignment film; irradiating the flat surface of the convex lens with a light source such that the alignment film is formed into an alignment structure, the alignment structure comprising a plurality of annular grooves nested from inside to outside, the orthographic projection of the plurality of annular grooves on a layer where the annular electrode lines reside being located in a spacing region of the at least two spaced apart annular electrode lines; adding a plurality of liquid crystal molecules into the alignment structure such that the plurality of liquid crystal molecules enclose a plurality of annular structures nested from inside to outside. The problem that the quality of the displayed picture is poor can be alleviated or mitigated, and the effect of enhancing the quality of the displayed picture can be achieved.
