Title:
Polarizing plate and manufacturing method of polarizing plate
Document Type and Number:
Japanese Patent JP6285131
Kind Code:
B2
Abstract:
A polarizing plate having an excellent optical property and a method of manufacturing the same. The polarizing plate includes: a transparent substrate transmitting light in a used bandwidth; an absorbing layer having 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 layer arranged 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 layer arranged 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 layer and the reflective layer are layered on the transparent substrate in this or reversed order.
