The present invention provides a pixel array, a display panel and a display device, and the pixel array includes a plurality of gate lines and a plurality of data lines intersecting and insulated from each other, and a plurality of pixel units defined by the plurality of gate lines and the plurality of data lines intersecting each other. Each of the plurality of pixel units includes a thin-film transistor and a strip-shaped electrode, the strip-shaped electrodes of two adjacent pixel units in a same column have different inclination directions, the thin-film transistors of the two adjacent pixel units are in inclination angle regions of the two adjacent pixel units, respectively, and the inclination angle region is a region corresponding to a position at which extending directions of the strip-shaped electrode and the gate line intersect to form an acute angle in a pixel unit.
