Abstract: A liquid crystal display panel and a display device are provided, and in the liquid crystal display panel, a common electrode is divided into a plurality of sub-common electrodes (01) arranged side by side in the extending direction of the gate lines; different common electrode signals are applied to the plurality sub-common electrodes (01), and their voltage magnitudes gradually increase in a transmitting direction of gate signals over the gate lines. Therefore, the inconsistency of the offsets ΔVp in the voltages of individual pixel electrodes in the entire liquid crystal display panel caused by the delay due to resistance and capacitance is compensated for by the voltages on the sub-common electrodes (01), so as to improve the picture quality of the liquid crystal display panel.
