Abstract
Disclosed is a backlight unit which illuminates a display panel from a rear surface thereof, including at least: tubular lamps arranged in parallel to the panel; and a reflecting member which reflects light from the lamps toward the panel, wherein the reflecting member is divided into a first region opposed to an area near an electrode provided in an end portion of the lamp and a second region nearer to a middle area than the first region, the first region having a higher reflectance than the second region. In another backlight unit, a reflecting member is divided, with respect to the arrangement direction of the lamps, into an end lamp near region which is opposed to a lamp arranged in end portion and a middle region which is nearer to a middle area than the end lamp region, the end lamp region having a higher reflectance than the middle region.
