Abstract: Provided are a block copolymer pattern formation method that enables formation, over a large area, of a block copolymer pattern with a perpendicularly oriented lamellar structure enabling nanoscale surface shape control, and a diffraction limited optical element produced using the block copolymer pattern formation method. The block copolymer pattern formation method is a method for forming a block copolymer pattern on a substrate and includes forming an oblique angle vapor deposited film on the substrate, applying a block copolymer onto the oblique angle vapor deposited film that has been formed, and subjecting the block copolymer that has been applied to perpendicularly oriented lamellar structure development post-treatment to form a pattern with a perpendicularly oriented lamellar structure.

Abstract: Provided are a polarizing plate having excellent optical characteristics, and a method for manufacturing the polarizing plate. The present invention is provided with: a translucent substrate through which light passes in a working band; a bundle structure layer constituted of a columnar sheaf comprising one or more material from among dielectrics, metals, and semiconductors, the bundle structure layer being formed on the translucent substrate; an absorption layer formed on the bundle structure layer; a dielectric layer formed on the absorption layer; and a reflection layer formed on the dielectric layer and arranged as a one-dimensional lattice at a pitch that is smaller than the wavelength of the light in the working band. Because the bundle structure layer increases light absorption and light scattering, the result is that reflectivity can be reduced and excellent optical characteristics obtained.
