Abstract
In a liquid crystal display device having a voltage-driven liquid crystal cell sandwiched between two spaced polarizers, the cell comprises a liquid crystal layer having a twisted molecular alignment with no applied voltage and also having an optical rotary power with respect to visible rays. In the vicinity of the cell or in close contact therewith, there is disposed an optically anisotropic layer having an optical rotary power smaller than that of the cell.
