  • Patent number: 8896921
    Abstract: A wire grid type polarization structure is disclosed. In one aspect, the polarization structure includes a retardation layer and a plurality of nanowires formed on the retardation layer. Each of the nanowires includes a wire core and a shell enclosing the wire core. The wire cores include metal nanoparticles embedded therein. The metal nanoparticles may absorb the visible lights effectively, so that the wire grid type polarization structure may have a desired polarization characteristic.
