摘要：
A prism sheet of an LCD includes a body part made of a transparent resin material and a plurality of polypyramid-shaped optical unit structures formed in a intaglio type on the body part. The plurality of optical unit structures have intaglio-type polypyramid shapes in an inside of their polygonal structure. A center of the intaglio portion corresponds to a vertex of the polypyramid, thereby forming a point.
