The present invention discloses a light guide plate, a backlight module and a display device, so as to solve the technical problem of color shift generated in prior art display panel due to the change of angle of view. The light guide plate comprises a bottom surface, a light exiting surface opposite to the bottom surface, and a quantum dot layer provided on the light exiting surface and comprising a quantum dot array, wherein the light exiting surface has a non-planar structure. Embodiments of the present invention provide following advantageous effects: the quantum dots on the surface of the light guide plate are configured to have a non-planar structure, such that the light transmitted through the spacing between quantum dots and having the same spectrum as the quantum dots is smoothly changed, thereby reducing the affection of color shift of the display device due to the change of angle of view.

Light guide plate, having quantum dot layer

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.
