Abstract
A backlight module includes a lighting unit including a primary light guiding unit and a light source, and an auxiliary light guiding unit. The light source is disposed at one side of the primary light guiding unit, and emits light toward the primary light guiding unit to be guided thereby for projecting in a first direction. The auxiliary light guiding unit includes a light collecting portion disposed at one side of the lighting unit opposite to the first direction for collecting light leaking from the lighting unit, and a light guiding portion extending generally transversely from one end of the light collecting portion for guiding the light collected by the light collecting portion to emit in a second direction different from the first direction.
