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. 一种背光单元可以包括光源、与光源相邻的导光板、设置在导光板上的低折射率层、设置在低折射率层上的阻挡层以及设置在阻挡层上并包括量子点的波长转换层。低折射率层的折射率可以小于导光板的折射率。
