Abstract: A light guide plate, a method of fabricating a light guide plate, a backlight module and a display device are disclosed. The light guide plate includes a light guide layer and a grating layer. The light guide layer includes a light incident surface, a light exit surface, and a bottom surface opposite to the light exit surface. The grating layer is disposed on a side of the light guide layer with the light exit surface being on the side and including a plurality of grating strips. The bottom surface is provided with a plurality of optical dots. The plurality of optical dots are configured to deflect light rays from the light incident surface toward the grating strips. The plurality of grating strips are configured to deflect light rays emitted from the light exit surface toward a normal line of the light exit surface.
