Abstract
Embodiments of the present disclosure are related to a backlight unit and a display device including the same, the backlight unit that a light source unit including a light source, and a light reflector surrounding the light source, and including at least one of a light reflection pattern, a light diffusion pattern, or a light source protection layer including a color conversion material is disposed can be provided. As an exposed electrode layer on a substrate is covered by the light reflector, a light efficiency can be improved by reducing a reflection loss by the electrode layer, and by various functions that the light source unit provides, a fabrication efficiency the backlight unit can be improved and the backlight unit having a thin thickness can be provided.
