A backlight module has a light guide plate and a frame, wherein the light guide plate includes at least a bump or at least a breach, and at least a pin is arranged on the frame, so as to the bump or the breach may be engaged with the pin. The pin on the frame not only fixes and positions the light guide plate but also prevents the light guide plate from leaking light and enhances the structure strength.
