Provided is a self-supporting film that has an anti-reflection function independently, so that the self-supporting film exhibits excellent optical characteristics as a result. A self-supporting film has a rugged-structure layer having periodic rugged shapes formed on a surface thereof, with these periodic rugged shapes being formed on at least one surface. The average thickness of the self-supporting film ranges from 0.2 &#x3bc;m to 20.0 &#x3bc;m. The rugged-structure layer has a yield strain of 1% or greater and a tensile elongation of 10% or greater.

Self-supporting film, self-supporting structure, method for manufacturing self-supporting film, and pellicle

A dielectric layeris formed on a region including grid-shaped convex portionsof a resin substratehaving the grid-shaped convex portionswith pitches of 80 nm to 120 nm on its surface, and metal wiresare formed on the dielectric layer. It is thereby possible to obtain a wire grid polarizer having a microstructural concavo-convex grid with pitches of the level of 120 nm or less that has not been implemented.

Method of manufacturing a wire grid polarizer

A wire grid polarizer has mainly a resin substratehaving grid-shaped convex portions, a dielectric layerprovided to cover the grid-shaped convex portionsof the resin substrateand at least part of side facesof the portions, and metal wiresprovided on the dielectric layer. The wire grid polarizer has a microstructural concavo-convex grid structure having grid-shaped convex portions, is not limited in structure, and has both the excellent degree of polarization and excellent transmittance over a wide range in the visible region.
