The utility model relates to the technical field of touch screens, and particularly discloses a low-reflectivity capacitive touch screen, which is provided with a touch screen cover plate, a priming coat and an AF (anti-glare) film layer, and the priming coat and the AF film layer are overlaid on the touch screen cover plate. The utility model provides a capacitive touch screen with low reflectivity. Compared with a traditional multilayer film anti-reflection scheme, the method is simple; only an anti-fingerprint AF film layer is reserved; a SiO2 priming coat is designed between the AF film layer and the touch screen cover plate; film layers are few and the film thickness is easy to control; the yield is high; the cost is low; color difference easy to control, under the condition that therefractive indexes of the touch screen cover plate, the SiO2 priming coat and the AF film layer are fixed, the surface reflectivity of the touch screen cover plate can be below 3% by adjusting the thicknesses of the SiO2 prim
