The invention provides a display touch-screen structure and a manufacturing method thereof. The touch-screen structure comprises base chemically-reinforced glass, an upper conductive layer and a lower conductive layer; the upper conductive layer comprises a PET film and an ITO film coated on the surface of the PET film; the lower conductive layer is formed by the ITO film which is directly manufactured on the surface of the base chemically-reinforced glass; and isolating points are arranged between two ITO films. The manufacturing method comprises the following steps: a continuous magnetron sputtering coating machine and an ITO ceramic target are adopted to coat the ITO film on the chemically-reinforced glass; the work gas is Ar and the pressure is between 0.1 and 1 Pa; the coating temperature is between 100 and 390 DEG C; and the coating pace is between 1.5 and 6 minutes. The invention not only simplifies the manufacturing process of the touch-screen, enhances the yield of products and reduces the manufacturing cost but guarantees that the intensity of the chemically-reinforced glass cannot be changed.
