A display panel, a display device and a driving method are provided. In the display panel, subpixels input with a first voltage data signal and subpixels input with a second voltage data signal are alternately arranged, and among the subpixels with a same color in a same row, the number of the subpixels input with the first voltage data signal with a positive polarity is equal to the number of the subpixels input with the first voltage data signal with a negative polarity; two adjacent pixel groups in a same column adopt contrary polarity driving manners.
