摘要

I will provide a transmission type liquid crystal display device and backlight unit using a prism sheet, the prism sheet. A prism sheet 10 for changing the traveling direction of the light by reflecting the light beams L to be incident concluded intensity distribution within a predetermined angular range, the prism sheet of the present invention, which extends to the top 18a of the seat base 12 reflection surface for totally reflecting the light rays L are composed of higher order surface 18 and a surface different from the surface of the small curvature and a small surface curvature of at least. The present invention provides a liquid crystal display device and an backlight unit to include a prism sheet as described above.
