    摘要: A polarized diffractive filter contains cyclic concave/convex portions formed as a diffractive grating on a transparent substrate. The concave portions are filled with an optical material. At least one member selected from the group consisting of i) a material constituting the concave/convex portions, and ii) the optical material filled in the concave portions contains a liquid crystal material. The diffractive grating contains an isotropic material, the isotropic material having a refractive index outside a range from an extraordinary index to an ordinary index of the liquid crystal material. The polarized diffractive filter is capable of receiving light having at least two different peak wavelengths so as to shield light of at least one of the peak wavelengths by diffraction and to transmit the light of the other peak wavelengths.
