Abstract
The present invention is a liquid crystal display with an improved backlighting system. A light source in the backlighting system radiates light in a first non-preferred direction. An optical apparatus coupled to the light source receives the light radiated by the light source in the first non-preferred direction and refracts it into a first preferred direction.
