Abstract
A backlight unit may include a wall and a plurality of light sources. The wall may have a side in a cross-sectional view of the backlight unit. The side may have a curved shape in the cross-sectional view of the backlight unit. The plurality light sources may include a first light source and a second light source. The second light source may be positioned farther away from a center portion of the wall than the first light source in the cross-sectional view of the backlight unit. A minimum distance between the second light source and the side may be greater than a minimum distance between the first light source and the side in the cross-sectional view of the backlight unit.
