| description | The disclosure provides a light guide plate, a backlight module and a display device. The light guide plate comprises a light guide plate body and a through hole, wherein the through hole is disposedon the light guide plate body, the light guide plate body further comprises a first light emitting surface that surrounds the side wall of through hole and is set as a profiled surface; the profiled surface can be specifically set as an oblique plane, a quadric surface and a freeform surface. When the light emitted by the light source passes through the light guide plate in the backlight module, multiple reflections and refraction occur, so that the light is incident on the through hole and the boring area of the display panel as much as possible. At the same time, the first light-emitting surface is adjusted to ensure the consistency of the light intensity in the display area.
