Abstract: The present invention discloses a liquid crystal display panel and a display device. A capacitance compensation portion is arranged using a shading region, and the capacitance compensation portion is arranged opposite to a portion of a common electrode located within the shading region. Compared to the case where a common electrodes and a pixel electrode are overlapped only in a light transmitting region, the present invention enlarges the overlap area of the pixel electrode and the common electrode in the shading region, compensates the storage capacitance between the pixel electrode and the common electrode, and reduces the voltage difference before and after jump of the voltage of the pixel electrode, and improves the flicker of a liquid crystal display panel. Moreover, as the capacitance compensation portions additionally provided in the pixel electrodes are located within the shading region, the aperture rate of pixel regions will not be influenced.
