Abstract
A polarizing plate having an excellent optical property and a method of manufacturing the same. The polarizing plate includes: a transparent substratetransmitting light in a used bandwidth; an absorbing layerhaving at least a metal-containing semiconductor layer containing a metal, the absorbing layer being arranged as a one-dimensional lattice shaped wire-grid structure having a pitch smaller than the wavelength of the light in the used bandwidth; a dielectric layerarranged as a one-dimensional lattice shaped wire-grid structure having a pitch smaller than the wavelength of light in the used bandwidth; and a reflective layerarranged as a one-dimensional lattice shaped wire-grid structure having a pitch smaller than the wavelength of light in the used bandwidth, wherein the absorbing layer, the dielectric layerand the reflective layerare layered on the transparent substratein this or reversed order.
