The invention discloses a display panel and a display device. When a pixel circuit in the display panel works in a data writing stage, the clock pulse frequency of a clock signal is a first frequency F1; when the pixel circuit works in the holding stage, N stages are set, in at least one stage of the N stages, the clock pulse frequency of the clock signal is second frequency F2, and F1 > F2 > 0. Therefore, on one hand, the power consumption of the display panel is saved, and on the other hand, the problem that the output signal is unstable due to the fact that the transistors of the driving circuit are in the same state for a long time when the clock signal is kept at the constant potential for a long time is solved.
