Abstract: The present invention discloses a method of forming an optical sheet. The method comprises: providing a mold having a first surface; forming a plurality of first concave shapes on the first surface of the mold such that the first surface of the mold is changed to a second surface of the mold; forming a plurality of second shapes on the plurality of first concave shapes such that the second surface of the mold is changed to a third surface of the mold; and using the third surface of the mold to emboss a film on a substrate to form a composite structure corresponding to the combination of the plurality of first concave shapes and the plurality of second shapes.

Abstract: The present invention discloses a method of forming an optical sheet. The optical sheet comprises a substrate and a film. The substrate has a first surface and a second surface opposite to the first surface. The film has a third surface and a fourth surface opposite to the third surface. The third surface of the film is on the first surface of the substrate. The fourth surface of the film comprises a structure corresponding to a combination of a plurality of first convex shapes and a plurality of second convex or concave shapes superimposed on the plurality of first convex shapes.
