The module includes a backlight unit having a lamp and a light guide plate disposed on a support main. A stopper protrudes from the support main into the light guide plate. A step coverage is defined at the light guide plate which includes an incline plane and is restrained by the stopper. Accordingly, a crack of the stopper caused by an external impact and light leakage caused by the crack is prevented.
