The invention provides a touch display screen. The touch display screen comprises a first substrate, a liquid crystal module, a filter layer, a second substrate and a first polaroid, wherein the first substrate, the liquid crystal module, the filter layer, the second substrate and the first polaroid are stacked in sequence; the surface, facing one side of the liquid crystal module, of the first substrate is provided with TFT (thin film transistor) electrodes; one side, facing the liquid crystal module, of the second substrate is provided with common electrodes; the TFT electrodes and the common electrodes are used for jointly controlling the arrangement state of liquid crystal molecules in the liquid crystal module; the touch display screen also comprises a transparent conducting layer arranged on the surface, backing on to one side of the liquid crystal module, of the second substrate or the surface of the first polaroid; the transparent conducting layer comprises a matrix and conducting nanometer wires filled in the matrix; the matrix is solidified transparent photosensitive resin; the transparent conducting layer is patterned to form touch electrodes; the touch electrodes are matched with the common electrodes to form a double-layer touch induction structure, and the double-layer touch induction structure is used for determining coordinates of a touch point. The touch display screen has the characteristics of being thin and low in production cost.
