Abstract: A condensing sheet, a backlight unit and a liquid crystal display device using the same are disclosed. The condensing sheet includes a base film, and a plurality of condensation patterns formed on the base film, wherein a first area and a second area are alternately defined on an upper surface of the base film, at least two condensation patterns are arranged in the first area, and a flat surface is formed in the second area, and wherein a width of each of the condensation patterns may be greater than a width of the flat surface.

Abstract: Disclosed herein is a backlight unit in which a viewing angle of a liquid crystal display device may be easily enlarged or changed. The backlight unit includes a light source, a light guide plate formed below a liquid crystal panel and including a light emitting surface through which incident light supplied from the light source is emitted toward the liquid crystal panel, a prism sheet formed between the light guide plate and the liquid crystal panel, and a plurality of protrusion patterns formed on one surface of the light guide plate which is opposite to the light emitting surface thereof, each of the plurality of protrusion patterns including a first prism which extends in a first direction and at least one second prism which extends in a second direction intersecting with the first direction, comes into contact with the first prism, and is shorter than the first prism.
