Abstract: A light guiding bar includes first and second light incident portions, a light exit portion and a reflecting portion. The first and second light incident portions are at opposite ends of the light guiding bar and receive light. The light exit portion extends in a first direction, and partially totally reflects and partially emits the light according to an incident angle. The reflecting portion extends in the first direction, is adjacent to the light exit portion and includes a plurality of reflecting surfaces. Each of the reflecting surfaces has a wedge shape and reflects the light in a direction inclined with respect to a second direction substantially perpendicular to the first direction. The light incident into the first and second light incident portions and directly on the light exit portion is totally reflected by the light exit portion.
