Abstract:
1. A polarizing element comprising: a first layer formed on a substrate, the first layer including: a plurality of first needle-shaped particles that has transmittance for a first polarized light having, a first polarization state, wherein the transmittance for the first polarized light is different from transmittance for a second polarized light in a second polarization state different from the first polarization state, in a first wavelength region; and a plurality of second needle-shaped particles that has transmittance for the first polarized light that is different from transmittance for the second polarized light, in a second wavelength region different from the first wavelength region, wherein both the plurality of first needle-shaped particles and the plurality of second needle-shaped particles are dispersed in the first layer, and wherein the plurality of first needle-shaped particles are comprised of a first material and the plurality of second needle-shaped particles are comprised of a second material that is different from the first material.
