A touch display panel comprises a color film substrate, which comprises a conducting layer arranged on a transparent substrate. The conducting layer comprises a plurality of first and second wires, and a color resistance insulating layer lying flat on the conducting layer, where the color resistance insulating layer includes first color resistances with via holes and second color resistances without via holes. The color film substrate also includes a plurality of bridges formed on the color resistance insulating layer, where at least one second color resistance has an extension portion extending in a direction substantially perpendicular to the second color resistances, where the extension portion isolates the conducting layer from the bridges between adjacent second color resistances.
