Abstract: The present embodiment comprises: a plurality of light-emitting units; and a reflector including reflector units having spaces formed to receive the plurality of light-emitting units, respectively. Each of the plurality of light-emitting units includes an LED package mounted on a substrate and a light diffusion layer having a groove portion formed on a surface opposite to the substrate in the LED package, wherein the outer circumference of the light diffusion layer faces the inner surface of a reflector unit. In the reflector, the plurality of reflector units are integrally formed, the spaces expand along a direction extending away from the substrate, and a wall forming each of the spaces surrounds the outer circumference of each of the LED package and the light diffusion layer.

Abstract: A display device is disclosed. The display device according to the present disclosure includes a frame; a light assembly disposed in at least one edge area of the frame; a panel positioned in front of the frame; and a light guide plate positioned between the frame and the panel so that light emitted from the light assembly is transferred to the panel, wherein the light assembly includes a light source and a filter positioned at a light path between the light source and the light guide plate and changing characteristics of light emitted from the light source. The present disclosure can improve display quality of the display device by changing characteristics of light emitted from the light source.
