Abstract
A high-contrast reflective liquid crystal display device of a lamination type in which scattering in the focal conic state of cholesteric liquid crystal has been reduced is described. The reflective liquid crystal display device has two or more laminated liquid crystal panels respectively having a liquid crystal layer of the cholesteric liquid crystal having different selective reflection wavelengths and the liquid crystal panel having a liquid crystal layer into which the liquid crystal having a longer selective reflection wavelength has been implanted has a smaller orientation regulating force of the liquid crystal layer applied to the panel.
