Abstract

Provided is a backlight unit comprising a light source body with at least one channel for generating a light; and a lens sheet with a first and a second surfaces, a plurality of lenses being formed on the first surface. The lens sheet is disposed in such a way that a boundary between neighboring lenses faces a light-emitting part of the channel.
