The invention relates to a touch display panel which comprises a plurality of scanning lines, a plurality of data lines and a plurality of touch sensing units; each touch sensing unit comprises a first pixel unit, a second pixel unit and a third pixel unit; each pixel unit comprises a pixel electrode, a storage capacitor electrode and a compensation capacitor, wherein a storage capacitor is arranged between the pixel electrode and the storage capacitor electrode, and the compensation capacitor is connected between the pixel electrode and scanning lines; and the capacitance ratio of the storage capacitors of the first, the second and the third pixel units and that of the compensation capacitors of the first, the second and the third pixel units are both equal to the area ratio of the pixelelectrodes of the first, the second and the third pixel units. The invention has the advantage that screen flicker can be reduced.
