A manufacturing method of a touch display panel is disclosed and has steps of depositing a touch-control metal layer on ail inner side of a color-filler substrate and patterning the touch-control metal layer; depositing a black matrix layer on the inner side of the color-filter substrate and patterning the black matrix layer; depositing a color photoresist layer on the inner side of the color-filter substrate and patterning the color photoresist layer; depositing a common electrode layer on the inner side of the color-filter substrate and patterning the common electrode layer; and performing cell-assembling to assemble the color-filter substrate and an array substrate together.
