<P>PROBLEM TO BE SOLVED: To provide a lens film which has small warpage even when a transparent base is thin, to provide a manufacturing method of the lens film, and to provide a display device provided with the optical film. <P>SOLUTION: Pole prisms 12B2 made of a curable resin are arranged along the extension direction on the transparent base 12B1 made of a flexible material. The transparent base 12B1 has a depression 12B5 corresponding to a valley part 12B3 between the pole prisms 12B2 adjacent to each other and, therefore, there is not a layer which does not function as a prism, that is, a skirt layer between the transparent base 12B1 and the pole prisms 12B2. Therein, when the thickness of the transparent base 12B1 is D2, and the height of the pole prisms 12B2 is D3, D2 and D3 satisfy the relation: 0.3≤D3/D2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
