Zusammenfassung:The utility model relates to a capacitive touch screen. The screen comprises a base plate provided with an air surface and a film surface, and touch screen film layers arranged on the film surface side of the base plate, wherein the touch screen film layers consist of an ITO layer, an insulation layer, a conductive layer and a film layer protection layer; running metal wires are distributed around the base plate and arranged in the conductive layer; and a masking film layer is further arranged between the film surface of the base plate and the touch screen film layers to cover the running metal wires. The utility model has the advantages that the masking film layer which is arranged between the film surface of the base plate and the touch screen film layers and capable of covering the running metal wires eliminates the use of a transparent cover plate arranged on the air surface side of the base plate, thereby improving the transmittance of a touch screen panel, reducing the reflectivity of the film layers, a
