Abstract: A structured polarizer includes a substrate including a dielectric material including elongated metal particles embedded to form a polarizing layer including a plurality of first polarizing regions having first elongated metal particles collectively aligned along a first direction and a plurality of second regions having second metal particles, the first polarizing regions and the second regions adjoining each other, the first metal particles being in the same plane as the second metal particles, a degree of polarization with respect to the first direction in the first polarizing regions at between 0.5 ?m and 1 ?m from a boundary between the first polarizing regions and the second regions being more than 90%, and a degree of polarization with respect to the first direction in the second regions at between 0.5 ?m and 1 ?m from the boundary between the first polarizing regions and the second regions being less than 10%.

Abstract: A structured polarizer (linear polarizing filter) with side-by-side in a plane (lateral) regions having different polarization directions, complete extinction and complete transparency, is presented with two superpositioned planes (polarizers) with a polarizer whose surface can be structured. The polarization properties of a plane is structured in such a way and the planes are mutually oriented in such a way that polarizing regions with different polarization directions and/or polarization properties, such as contrast, polarization-direction-dependent absorption properties as a function of the wavelength, and/or non-polarizing regions, such as transparent or opaque and/or regions having a predefined absorption for specified wavelengths are obtained.
