Abstract: Display apparatus includes LEDs, bottom chassis to accommodate the LEDs; and reflective member disposed on the bottom chassis. The reflective member includes a reflective bottom portion, and a reflective inclined portion obliquely formed to face a rear surface of the display panel which includes first regions that respectively correspond to LEDs located adjacent to the reflective inclined portion, and second regions each provided between two neighboring first regions and has a reflective characteristic different from a reflective characteristic of a neighboring first region. Second regions and neighboring first regions are on the reflective inclined portion having a uniform incline angle with respect to a side edge of the reflective bottom portion, the first regions include a group of light adjusting members, and the group of light adjusting members of each of the first regions is disposed to correspond to one of the LEDs disposed adjacent to the reflective inclined portion.
