<p>A backlight unit includes a light guide panel (13) to guide entering light, a light source (16) disposed on at least one side of the light guide panel to emit light, and a reflecting sheet (20) disposed on a surface of the light guide panel to reflect the entering light toward a light emitting plane of the light guide panel, and includes a plurality of reflecting areas (21,23,25) which have different reflectance, where a reflecting area of the plurality of reflecting areas which encounters a relatively large amount of the entering light has a higher reflectance than that of a reflecting area of the plurality of reflecting areas which encounters a relatively small amount of the entering light.</p> |
