Abstract
A backlight for a liquid crystal display includes a light guide plate located adjacent to a liquid crystal display panel. A light collector is located at one end of the light guide plate and has an exposed surface for receiving ambient light. The light collector has a reflector secured inside it. The received ambient light is reflected by the reflector along the light guide plate. The reflector may include three arcuate shaped reflecting elements. The light guide plate has a reflective surface which reflects the light toward the liquid crystal display panel.
