Abstract
A backlight module includes lamps and two light guide plates facing each other. The lamps are interposed between the two light guide plates. Each of the two light guide plates includes an incident surface and an emitting surface. The incident surface includes a number of first protrusion groups corresponding to the lamps and a number of second protrusions respective between the two adjacent first protrusion groups. The emitting surface includes a number of concave surfaces respectively corresponding to the first protrusion groups. This invention also provides a light guide plate and a method of making the light guide plate.
