Beschreibung
Zusammenfassung:	A display device is provided. The display device includes: a substrate; and at least one light assembly separately located on the substrate, wherein the light assembly includes: a light source; and a lens configured to shield an upper surface and a side surface of the light source, wherein the lens includes: a refraction portion separately located on the upper surface of the light source; and a reflection portion separately located at the side surface of the light source. Thereby, the lens includes a reflection portion located at a side surface of the light source, thereby improving light efficiency of a backlight unit.
