Abstract
A backlight module includes a light guide plate, a light source disposed at a side of the light guide plate, a diffuser sheet positioned over the light guide plate but not directly contacting the light guide plate, and a light mixing space positioned between the light guide plate and the diffuser sheet so that light emitted from the light guide plate efficiently mixes in the light mixing space before entering the diffuser sheet and being emitted out of the backlight module.
