PURPOSE: An optical sheet, a backlight unit and a liquid crystal display device including the same are provided to diffuse a light emitted from a light source by including a plurality of beads inside a protrusion part. CONSTITUTION: An adhesive part(130) is positioned on a first material(120). A second material(140) is positioned on the adhesive part. A protrusion part(170) is positioned on the second material. Difference of a refractive index of the first material and a refractive index of the second material is 0.04~0.2. The protrusion part is one of a prism, a lenticular lens, or a micro lens. The protrusion part includes a base part.
