Light guide plate, backlight module and display device

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. 本揭示提供一种导光板、背光模组及显示装置。导光板包括导光板本体及通孔，通孔设置在导光板本体上，导光板本体还包括第一出光面，第一出光面为环绕所述通孔的侧壁，第一出光面设置为异形面。异形面具体的可设置为斜平面、二次曲面及自由曲面。发光源发出的光线在经过背光模组内的导光板内时，发生
