PROBLEM TO BE SOLVED: To provide a twisted nematic liquid crystal display device which has its display contrast, gradation characteristics, and field angle characteristics of display colors improved. SOLUTION: This device consists of a driving twisted nematic liquid crystal cell consisting of at least one compensation film which is formed of optically positive uniaxial liquid crystal macromolecules and has the nematic hybrid orientation that the liquid crystal macromolecules form in a liquid crystal state fixed, a couple of transparent substrates equipped with electrodes, and a nematic liquid crystal sandwiched between the substrates and two polarizing plates which are arranged above and below the liquid crystal cell. Here, the product (Δnd) of the refractive index anisotropy (Δn) of the nematic liquid crystal constituting the liquid crystal cell and the thickness (d) of the liquid crystal layer of the liquid crystal cell is 200 to 500 nm. |
