Abstract
The present invention discloses a light guide plate, a backlight module and a display device. The light guide plate comprises a light conversion layer, the light conversion layer is arranged at a light emitting plane of the light guide plate for receiving a first light and converting the same to at least a second light to emit. According to the aforesaid aspect, the present invention can improve the display effect of the display device by making the emitted light have a better diffusivity and a larger brightness view angle.
