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.

A polarization converting system and a method of manufacturing the same are provided. The polarization converting system includes a polarization splitting unit splitting incident unpolarized light into two orthogonal polarizations and a polarization converting unit converting incident light into specific polarized light. The polarization converting unit has first and second regions that correspond to the polarization splitting unit and are different in a polarization converting extent from each other.

A light source lens includes a refraction surface having a concave portion proximate to a central axis of a light source lens. The central axis passes through a light source that is coupled to the light source lens. An angular distribution function F(θ′) of a first light emitted from the light source and refracted at the refraction surface at least approximately satisfies F ( θ ′ ) ∝ 1 cos 3 ( θ ′ ) , where θ′ is a latitude angle of the first light refracted at the refraction surface with respect to the central axis. The lens refracts a light emitted from the light source so that the resulting luminance at the upper area of the light source is more uniform.
