초록 ▼

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.

대표청구항 ▼

[ What is claimed is:] [1.] A surface-type prism sheet having a shape of a periodic pattern for use with a surface light source, each periodic pattern comprising:a plurality of surfaces extending to one direction,wherein a cross section of said each periodic pattern has at least four surface slopes extending to an orthogonal direction with respect to adjacent surface slopes of said each periodic pattern, each of said at least four surface slopes faces opposite to said adjacent surface slopes of said each periodic pattern,wherein said at least four surface slopes of said each periodic pattern include two distal surfaces having first cross sectional widths and two proximal surfaces having second cross sectional widths different from said first cross sectional widths, andwherein said first cross sectional width is longer than said second cross sectional width.
