Light guide plate, backlight module and display device

Abstract

The present invention is directed to a light guide plate, a backlight module and a display device with the light guide plate comprising a bottom surface containing space for holding light sources, a light emitting surface opposite the bottom surface and a quantum dot layer is arranged in the containing space in the direction of the light emitting surface. Since the bottom surface of the light guide plate is provided with the containing space for holding the light sources, and the light sources are limited within the containing space, light diffusion due to the fact that the light sources are positioned outside the light guide plate is reduced, loss of light is reduced, and quantity of the light sources in the backlight module is reduced. Since the quantum dot layer is arranged in the containing space toward a direction of the light emitting surface, white mixed light is formed according to fluorescent effect of quantum dot materials. Further, as the quantum dots have the characteristics of high color gamut and high transmittance, display effect can be improved.
