Abstract
A backlight unit may include a light source, a light guide plate neighboring the light source, a low refractive index layer disposed on the light guide plate, a blocking layer disposed on the low refractive index layer, and a wavelength conversion layer disposed on the blocking layer and including quantum dots. A refractive index of the low refractive index layer may be less than a refractive index of the light guide plate.
