Abstract
A light guide plate, a method of manufacturing a light guide plate, a backlight module, and a display device are disclosed. A reflective layer is provided within the light guide plate, and the reflective layer is located in the path of the parallel incident light for reflecting the parallel incident light so that the parallel incident light exits from the light exit surface. The parallel incident light is an incident light parallel to the light exit surface. Without the a reflective layer, the parallel incident light propagates linearly within the light guide plate and exits from the opposite surface of the light entrance surface. The reflective layer changes the original linear path of the reflective layer and makes the parallel incident light continue to propagate in other directions within the light guide plate.
