  • Patent number: 8300187
    Abstract: A reflective liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer, a first alignment layer, and a second alignment layer. The first substrate and the second substrate are disposed oppositely to each other. The liquid crystal layer is disposed between the first substrate and the second substrate. The liquid crystal layer includes a plurality of liquid crystal molecules for reflecting light within a wavelength range and allowing light beyond the wavelength range to pass through. The second alignment layer is disposed on an inner side of the first substrate facing the second substrate, and the second alignment layer is employed to absorb the light passing through the liquid crystal layer and align the liquid crystal molecules.
