Die for moth-eye, and method for producing die for moth-eye and moth-eye structure |
| 摘要 |
A mold of an embodiment of the present invention has a surface that has a shape which is inverse of a surface shape of a moth-eye structure. This surface has a plurality of protrusions, a plurality of ridges extending between the plurality of protrusions via saddle portions, and a plurality of holes, each of which is defined by at least any three of the plurality of protrusions and ridges extending between the at least any three of the plurality of protrusions, and an average distance between centers of adjacent holes, p, and an average depth of the saddle portions, r, satisfy the relationship of 0.15≦r/p≦0.60. |
