Abstract:
1. A wire grid polarizer comprising fine metal wires arranged parallel to one another and thus transmitting TM-polarized light, wherein a light absorbing layer for absorbing TE-polarized light is provided on at least one of the surfaces of the wire grid polarizer and consists of composite fine lines, each fine line being a lamination of a plurality of composite layers, each composite layer consisting of a pair of a dielectric wire layer and a metal wire layer, and the composite layer being repeatedly stacked on each fine metal wire of the wire grid polarizer so that the dielectric wire layer and the metal wire layer are alternately stacked, wherein a refractivity of a dielectric material of the dielectric wire layer is not less than 1.8 for the visible spectrum of light, and wherein a metal of the metal wire layer of the lamination has a real part of complex refractive index of not less than unity and an extinction coefficient of not less than unity.
