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.

A prism sheet capable of achieving an enhancement in light efficiency and viewing angle characteristics and a backlight unit using the prism sheet are disclosed. The prism sheet includes: a condensing film which transmits light incident to the condensing film; a plurality of prism crests on the condensing film having apexes; and a plurality of reflection patterns formed on the condensing film such that each of the reflection patterns faces a boundary of adjacent prism crests associated with the reflection pattern to reflect light incident onto the reflection patterns.

Provided are an optical sheet, a backlight unit and an LCD device having the same. The backlight unit includes a first layer, a second layer, and a refractive pattern. The first layer has a larger refractivity than an air layer, and the second layer has a larger refractivity than the first layer. The refractive pattern is disposed at a boundary surface between the first layer and the second layer and has ridges and furrows that change a traveling path of light. The optical sheet refracts light at least three times to condense the light in a direction perpendicular to a light-exiting surface.

The present invention relates to an optical efficiency enhancing film and an LCD using the same. The LCD of the present invention is provided with an optical efficiency enhancing film that includes uniaxial films made of a refractive index anisotropic material and isotropic films, wherein the uniaxial films and the isotropic films are alternatively laminated. Then, optical efficiency as well as polarization may be enhanced to thereby improve the brightness of the LCD.
