ABSTRACT:
A periodic pattern is formed on a surface of prism sheet, and the cross section of a minimal unit 14 of the periodic pattern is shaped like an M. The M-shape includes a long positive-sloping surface, a short negative-sloping surface, a short positive-sloping surface and a long negative-sloping surface 16b. By designing the prism sheet in such a manner, a portion of the light behaving in a side mode is converted to recurrent mode light, and the surface luminance is enhanced.
