Abstract

See full text

A polarizing plate having excellent optical properties includes: a transparent substrate that is transparent to light in a used wavelength band; grid-shaped protrusions arranged on the transparent substrate at a pitch shorter than the wavelength of light in the used band, extending in a predetermined direction, and has a reflective layer and a reflection control layer; and a groove which is recessed between the grid-shaped protrusions and whose width in a direction orthogonal to the predetermined direction is reduced to zero in the depth direction. This improves transmittance and reflectance properties, thereby achieving excellent optical properties.
