1. A backlight unit for a display device, comprising:
- a first optical sheet;
a light source to supply light to the first optical sheet;
a first antireflection layer on a surface of the first optical sheet, wherein the first antireflection layer includes colloid particles distributed on a surface of the first antireflection layer;
second, third and fourth optical sheets, wherein the four optical sheets are a diffusion sheet, first and second prism sheets, and a protection sheet; and
at least one second antireflection layer, the at least one second antireflection layer being disposed on surfaces of the second to fourth optical sheets, wherein the at least one second antireflection layer includes colloid particles distributed on a surface of the at least one second antireflection layer.
