| 摘要 |
A reflection liquid crystal display device comprising a liquid crystal cell where a liquid crystal layer is provided between two opposed electrode substrates, a reflecting layer, and a cholesteric liquid crystal film, characterized in that the ratio (SCE/SCI) of the specular component excluded-refelctance (SCE) to the specular component included-reflectance (SCI) of the cholesteric liquid crystal film is 15% or more, the wavelenght bandwidth of the cholesteric selective reflection ranges from 30 mm to 150 nm, and the center wavelength of the cholesteric selective reflection is in the visible range of 380-780 nm or in the near-infared range of 800-2000 nm.
