Abstract: A prism sheet, a back light unit and a liquid crystal display device using the prism sheet are provided to increase a brightness of the LCD device by forming a cross-section of the prism in a scalene triangle with an acute angle. A prism sheet includes a base film(142) and plural prism threads(144). The prism threads are formed on an upper surface of the base film. The prism threads have acute inner angles. Each of the prism threads includes first and second slant surfaces and an apex. The first slant surface is slanted from the base film by a first angle. The second slant surface is slanted from the base film by a second angle. The apex is formed by the first and second slant surfaces.

Abstract: A backlight unit and an LCD(Liquid Crystal Display) having the same are provided to maximize light reflection efficiency of a reflecting plate and prevent faults such as luminance non-uniform and bright line by uniformly diffusing light by the reflecting plate. A backlight unit(110) comprises a lamp(112), a reflecting plate(114) and an optical member(122). The reflecting plate upwardly reflects and diffuses light downwardly emitted from the lamp, and emits heat emitted from the lamp to the outside. The optical member improves luminance of light upwardly emitted from the lamp and the light upwardly reflected and diffused by the reflecting plate.
