Abstract: A display device includes a display panel including a display surface on which an image is displayed and a rear surface opposite to the display surface, and a backlight unit which is under the display panel and supplies a light to the display panel. The backlight unit includes a light source unit which emits a first light in a direction taken from the display surface to the rear surface, a reflection sheet which reflects the first light, and an active layer which is between the light source unit and the reflection sheet and includes a scattering particle which scatters the first light.

Abstract: A display apparatus includes a display panel which displays an image and a backlight unit which provides light to the display panel. The backlight unit includes a bottom chassis, a driving substrate, a laser light source, an optical unit, and an optical fiber. The bottom chassis includes a bottom surface and a sidewall. The laser light source emits laser light to the sidewall. The optical unit has an incident surface having a first area and into which the laser light from the laser light source is incident and an emission surface having a second area less than the first area and from which the laser light is emitted. The optical fiber receives the laser light from the emission surface, an end of the optical fiber is connected to the emission surface, recessed patterns are defined on the optical fiber, and the laser light is emitted through the recessed patterns.
