  • Patent number: 9995868
    Abstract: 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.
