<p>It is possible to provide an optical sheet set facilitating a user to visually and easily judging the number of optical sheets and the order of the optical sheets to be embedded in a backlight unit. Moreover, it is possible to provide a backlight unit and a liquid crystal display unit using the optical sheet set. The optical sheet set (10) is formed by optical sheets A, B, C superimposed on one another and arranged between a liquid crystal panel of a liquid crystal display device and a light source irradiating the liquid crystal panel from the rear surface. For the optical sheets A, B, C, coloring units "a", "b", "c" are arranged. The color of the coloring unit "b" is different from the color of the coloring unit "a" or "c" and the coloring unit "b" is partially overlapped with the coloring unit "a" and the coloring unit "c".</p> |
