    Abstract: To provide an inorganic polarizing plate which, when used in structures having different used wavelength bands, can reduce reflectance by using a common structure, making it possible to achieve a predetermined light extinction ratio. The inorganic polarizing plate has a substrate that is transparent to light in a used bandwidth, a reflective layer that is composed of grids that are formed on one surface of the substrate with a pitch that is smaller than a wavelength of light in the used bandwidth, a dielectric layer that is stacked on the reflective layer, and an absorbing layer containing FeSi fine particles.

    Abstract: Provided are: a polarizing plate having high transmittance characteristics and suppressed reflected light, and a manufacturing method thereof; and an optical device provided with said polarizing plate. A polarizing plate (100) having a wire grid structure comprises: a transparent substrate (1); and grid-like projection portions (20) arranged on the transparent substrate at a pitch shorter than the wavelength of light in a used bandwidth and extending in a predetermined direction. The grid-like projection portions (20) each have a reflective layer (3) and a dielectric layer (4) in order from the transparent substrate (1) side, wherein when viewed from the predetermined direction, the reflective layer (3) has at least one step on the side thereof and has the largest bottom width on the transparent substrate (1) side.

    Abstract: Provided are a pattern formation method and a method for manufacturing a polarizing plate using the pattern formation method, the pattern formation method having: a step for forming, on a substrate, a linear guide pattern which is arranged at a predetermined pitch and is compatible with a portion of block chains of a block copolymer, and a neutral pattern embedded in the pattern of the guide pattern; a step for forming a layer including a block copolymer on the guide pattern and the neutral pattern; a step for heat-treating the layer including the block copolymer and forming a lamellar structure in which lamellar boundaries are arranged perpendicular to the substrate by microphase separation of the block copolymer; and a step for selectively removing a portion of the block chains of the block copolymer and thereby forming a line-and-space-shaped fine pattern having a smaller pitch than the guide pattern.

    Abstract: Provided is a structural birefringence-type inorganic wave plate having excellent heat resistance and durability, and a fine pattern. Also provided is a manufacturing method for an inorganic wave plate by which, even in the case of a fine pattern, productivity is high, and a desired phase difference is easily achieved and stably obtained. This inorganic wave plate is obtained by utilizing a selective interaction between a polymer having a repeating unit containing a carbonyl group, and a metallic oxide precursor, the inorganic wave plate having a wire grid structure provided with a transparent substrate, and grid-shaped protruding portions arranged at a pitch shorter than the wavelength of light in a used band on at least one surface of the transparent substrate and extending in a predetermined direction, the main component of the grid-shaped protruding portion being a metallic oxide.
