Abstract
A backlight unit having improved luminance and reduced profile, and a liquid crystal display including the same are disclosed. In one embodiment, the backlight unit includes: i) a light source, ii) a light guiding plate including an incoming surface on which light generated from the light source is incident, an upper surface substantially perpendicularly extended with respect to the incoming surface, and a bottom surface arranged facing the upper surface and iii) an optical sheet formed on the light guiding plate. The upper surface of the light guiding plate includes a guiding surface, an incoming surface, and an emission surface sequentially arranged close to the incoming surface of the light guiding plate, and the optical sheet may be formed to cover the inclined surface and the guiding surface.
