First Claim
1. A diffuser with a light condensing function, comprising a substrate and a plurality of longitudinally arranged long strip-typed prism rods;
- one surface of said substrate being disposed with said plurality of prism rods;
each said prism rod being provided with a crest line, a first inclined face and a second inclined face;
said crest line being positioned at the highest position of said prism rod;
said first inclined face and said second inclined face being respectively extended from two sides of said crest line to said substrate;
at least one inclined face of said first inclined face and said second inclined face of each of parts of said prism rods being disposed with a diffusion face;

Abstract
One face of a substrate of a diffuser with a light condensing function is disposed with a plurality of prism rods; at least one inclined face of parts of prism rods is disposed with a rough diffusion face; the diffusion face may be positioned on any position of the inclined face of the prism rod; the diffusion face is disposed with a plurality of irregularly arranged raised and indented stripes perpendicular, not perpendicular or parallel to a crest line of the prism rod; chromatic dispersion can be reduced and stripes of the prism rods can be atomized effectively by utilizing the diffusion face to eliminate the occurrence of moiré fringes and elevate the yield factor.
