Abstract: A display device includes a display panel and a backlight unit adjacent to the display panel. A cover unit is adjacent to the display panel and the backlight unit. The backlight unit includes a light guiding structure including a first surface and a second surface facing each other in a thickness direction of the display panel. Side surfaces connect the first surface to the second surface. Signal lines are directly disposed on the first surface, the second surface, or a side surface of the side surfaces. A light-emitting diode package is coupled to the signal lines and is positioned to provide light to a. first side surface of the side surfaces.
