An optical sheet, a backlight unit including the same, and a liquid crystal display including the same are provided to reduce a manufacturing cost and a size thereof by simplifying an assembling process thereof. An optical sheet includes a base material(132), a light collection pattern(134), a light diffusion layer(136), and a low refractive index layer(138). The base material is used for transmitting incident light from the outside. The light collection pattern is formed on an upper part of the base material in order to collect the incident light from the outside. The light diffusion layer is formed at a lower part of the base material and diffuses the incident light from the outside. The low refractive index layer is formed between the base material and the light diffusion layer. |
