発明の名称 (英語) CIRCULAR POLARIZER PRODUCING METHOD AND CIRCULAR POLARIZER
発明の概要(英語) An object of the present invention is to provide a circular polarizer that exhibits, at an arbitrary wavelength, circular dichroism having a different polarity depending on an incident direction of light, and to provide a method for producing the circular polarizer. The present invention provides a method for producing a circular polarizer by forming a first film containing a chiral matter and forming a second film containing a light absorbing material on the first film. Further, a circular polarizer of the present invention is characterized in including: a first film containing a chiral matter; and a second film containing a light absorbing material provided on the first film. As the chiral matter, a biological molecule selected from saccharides, tartaric acid, vitamins, peptides, and proteins may be used. Further, as the light absorbing material, a low-molecular light absorbing material such as Rhodamine 6G or Nile blue can be used.
