Abstract: Provided is a depolarizing plate having a superior degree of depolarization to conventional depolarizing plates. The depolarizing plate includes a light-transmitting substrate having a surface layer portion in which a fine pattern is provided that includes a plurality of curved lines randomly disposed at a pitch of no greater than a wavelength of light, and that exhibits structural birefringence.

Abstract: There is provided an optical body including: a base material; a second optical layer, formed on at least one surface of the base material, that reduces a reflection of extraneous light; and a first optical layer, laminated on top of a part of the second optical layer, that extracts internally propagating light incident inside the base material from a side face of the base material to an outside of the base material. On a surface of the first optical layer, a first concave-convex structure that reflects the internally propagating light is formed.

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: There is provided a novel and improved optical body, method for manufacturing an optical body, light-emitting apparatus, and image display apparatus capable of improving emitted luminance and transparency, the optical body including: a base material; and a light extraction section, formed on at least one surface of the base material, that extracts internally propagated light incident inside the base material from a side face of the base material to an outside of the base material. The light extraction section includes a concave-convex structure in which at least one of concavities and convexities has a frustum shape, a fill ratio of the concave-convex structure is 15% or greater, and a light transmittance is 50% or greater.
