A novel method to produce multiaxial polarizers has been developed. A thin film of poly(4-methacryloyloxyazobenzene) was coated on a substrate plate and irradiated with linearly polarized light to induce the reorientation of the azo chromophore. An aqueous solution of a dye was spread on the film by the spin-coating technique to form a dichroic dye layer. The direction of the electric vector of the polarized light for the photoisomerization determined the orientation direction of dye molecules.
