The invention relates to a touch display panel and a display device. The display panel comprises a touch electrode layer, wherein the touch electrode layer comprises multiple equal-area touch regions; each touch region comprises a touch electrode and a clearance region; a display substrate comprises sub-pixels of multiple colors; the area of sub-pixels of one color among the sub-pixels corresponding to the clearance region of each touch region is same. By virtue of setting same area of color resistance layers of each color corresponding to a slit region in the equal-area touch region, light rays emergent from the slit regions in each touch region do not generate color cast, so as to ensure that the light rays penetrating through the touch electrode layer have no color cast on the whole and further avoid the occurrence of a Newton ring phenomenon.
