    摘要: A back light unit is disclosed, which improves condensing efficiency of light and viewing angle characteristics. The back light unit includes at least one lamp generating light, a light guide plate emitting light across a surface thereof using the light generated from the lamp, a diffusion sheet arranged above the light guide plate to diffuse the light passing through the light guide plate, a first condensing sheet condensing the light from the diffusion sheet using a plurality of first elliptical condensing patterns arranged on the diffusion sheet in a first direction, and a second condensing sheet further condensing the light from the first condensing sheet using a plurality of second elliptical condensing patterns arranged on the first condensing sheet in a second direction crossing the first direction.
