PURPOSE: A diffusion sheet, a backlight unit of a liquid crystal display device including the same, and a manufacturing apparatus thereof are provided to minimize brightness degradation by improving a hot-spot phenomenon generated by an LED lamp. CONSTITUTION: A liquid crystal display device comprises a liquid crystal panel(100) and a backlight unit(500) and is modularized using various parts. A liquid crystal panel is mounted on the inner side of a support main(300) and fixed by combining a case top(400) on the upper part of the liquid crystal panel. The backlight unit is comprised of a plurality of LED lamps(510), a lamp substrate(520), a lamp housing(530), a light guide plate(540), a diffusion sheet(550), a prism sheet(560), and a reflective plate(570). |
