The embodiment of the invention provides a display panel and a display device. A first sub-pixel in the display panel comprises a first pixel electrode, a second sub-pixel comprises a second pixel electrode, and a third sub-pixel comprises a pair of third pixel electrodes; in the same row, the extending directions of the first branch electrodes which are parallel to one another and are electrically connected are different from the extending directions of the second branch electrodes which are parallel to one another and are electrically connected, and the first branch electrodes and the secondbranch electrodes are in mirror symmetry about the column direction; in the same column, the first branch electrodes of any two adjacent first pixel electrodes are in mirror symmetry with respect tothe row direction, and the second branch electrodes of any two adjacent second pixel electrodes are in mirror symmetry with respect to the row direction; and a plurality of third branch electrodes which are parallel to one another and are electrically connected and a plurality of fourth branch electrodes which are parallel to one another and are electrically connected in the third pixel electrodeextend in different directions and are in mirror symmetry about the row direction.
