Disclosed are a backlight for providing an enhanced brightness of light with a lower consumption of electricity and a liquid crystal display device using thereof. A light guide plate has brightness enhancing recesses formed on a bottom surface thereof and light collecting grooves formed on an upper surface thereof. The brightness enhancing recesses efficiently reflect the light having different directions and the light collecting grooves collects the light reflected by the brightness enhancing recesses. A loss of the light generated by a lamp may be minimized, resulting in enhancing the brightness of the light. Thus, the consumption of the electricity can be greatly reduced.
