US Patent 7868973 Liquid crystal display device with two liquid crystal

An exemplary LCD device (2) includes a first substrate (21), a second substrate (22), a third substrate (23), a first liquid crystal layer (24), and a second liquid crystal layer (25). The first, second, and third substrates are arranged parallel to one another, and the first substrate is interposed between the second and third substrates. The first liquid crystal layer is interposed between the first substrate and the second substrate. The second liquid crystal layer is interposed between the first substrate and the third substrate. Optical rotations of the liquid crystal molecules of the first liquid crystal layer and the liquid crystal molecules of the second liquid crystal layer are reversed relative to each other, with the liquid crystal molecules of the first and second liquid crystal layers being arranged enantiomorphously at the respective opposite sides of the first substrate.
