A touch display panel may include a display unit and a touch unit. The display unit may include a first base substrate having a plurality of pixel electrodes, a second base substrate including a common electrode disposed on a first face of the second base substrate, and an electro optical layer disposed between the pixel electrodes and the common electrode. The first face faces the first base substrate. The touch unit includes a color filter layer including a plurality of color filters and a first electrode part including first electrodes disposed on a second face of the second base substrate, and a third base substrate including a second electrode part extended along a direction crossing the first electrodes. The first electrodes may be disposed on a boundary area of the color filters having different colors from each other, so that mixing of the colors is prevented.
