The present invention has disclosed a touch screen, comprising: a substrate; at least one first electrode formed on the substrate; at least one second electrode formed on the substrate, the first electrode and the second electrode having different extending directions, and there being an intersecting area between a vertical projection of the first electrode on the substrate and a vertical projection of the second electrode on the substrate; and a first protection layer formed at least at the intersecting area between the first electrode and the second electrode; wherein, the substrate is provided with a groove at the intersecting area between the first electrode and the second electrode so as to at least receive therein a portion of the first electrode located within the intersecting area. The present invention has also disclosed a display device and a method for manufacturing the touch screen. The present invention is provided to prevent two electrodes in two different layers from electrically contacting with each other and to ensure the yield of the touch screen to some extent.
