Abstract: A display apparatus includes a display panel curved along a first direction and a backlight unit. The backlight unit includes a bottom chassis, light emitting diodes, reflecting members, and a reflecting sheet. The light emitting diodes include a first light emitting diode and a second light emitting diode. The second light emitting diode is spaced apart from the first light emitting diode in the first direction. A first area that a first reflecting member disposed under the first light emitting diode among the reflecting members is exposed is different from a second area that a second reflecting member disposed under the second light emitting diode among the reflecting members is exposed.

Abstract: A backlight assembly includes a light guide member extending in a direction and having a light incident surface and a light exiting surface. A light source faces the light guide member and supplies light to the light guide member through the light incident surface. A reflecting member reflects light exiting from the light exiting surface of the light guide member. The reflecting member includes a groove receiving the light guide member. A first reflecting portion is disposed under the light guide member and reflects light refracted by the light guide member in an upward direction. A second reflecting portion is disposed on the light guide member and reflects light refracted by the light guide member in a downward direction.
