<p>PURPOSE: A backlight unit, a display apparatus using the same, and a lighting apparatus including the same are provided to minimize the deformation of an optical member due to the heat of a light source by emitting the heat by using a heat radiation part, and by supporting the optical member by using an upper cover plate. CONSTITUTION: At least one light source(142) is arranged between a first reflector(130) and a second reflector(132). An upper cover plate(120) and a lower cover plate(180) are separated from each other. A heat radiation part(160) supports the light source. The heat radiation unit is arranged between the upper cover plate and the lower cover plate to emit the heat of the light source.</p> |
