Backlight assembly and display device using the same

The invention emit heat emitted from the light generator to the outside, or, to a backlight assembly and a display device that can be dispersed effectively. The backlight assembly according to the invention is light-generating device, the receiving member, the first heat radiation member, wherein the heat insulating member that is connected to the first heat radiation member and the first heat radiation member connected to the storage member for storing said light-generating device in a second heat radiation member it is connected. The display device according to the present invention includes a display panel for displaying an image using light supplied from the backlight assembly and the backlight assembly. In addition, the heat insulating member to form an air layer instead of a separate substance, and the first heat radiation member and the second heat radiating member may be replaced by a radiation member. The heat radiation member, heat insulating material, a heat insulating layer, the light-generating device, a light emitting diode, the heat conductivity
