The invention discloses a display panel, comprising a plurality of data lines, scanning lines and common lines, and a plurality of first pixels and second pixels, wherein each common line comprises amain common electrode, a first branch common electrode and a second branch common electrode; the main common electrode, the first branch common electrode and the second branch common electrode of thesame common line are electrically connected, the main common electrodes and the scanning lines are distributed at intervals, and the first branch common electrodes and the second branch common electrodes are arranged adjacent to the data lines; the driving brightness of the first pixels is greater than the original brightness, each first pixel includes a first pixel electrode, and the first pixelelectrodes are partially overlapped with the first branch common electrodes to form a first storage capacitor; and the driving brightness of the second pixels is less than the original brightness, each second pixel includes a second pixel electrode, and the second pixel electrodes are partially overlapped with the second branch common electrodes to form a second storage capacitor. The invention also discloses a display device. According to the scheme of the invention, the flicker of the screen caused by backlash in the display panel can be reduced, and the display quality can be improved.
