1. A liquid crystal display device comprising:

  • a lower polarizer;

    a lower retardation plate formed above the lower polarizer, the lower retardation plate having a first lower retardation plate made of a discotic liquid crystal film with hybrid alignment and a second lower retardation plate made of a polymer film having a three-dimensional refractive index anisotropy, the second lower retardation plate being disposed below the first lower retardation plate and having a three-dimensional refractive index in a range of −

    0.7 to 0.7;

    a liquid crystal cell formed above the lower retardation plate, the liquid crystal cell having a nematic liquid crystal layer, the nematic liquid crystal layer having a twist angle set in a range of 0°

    to 70°

    ;

    an upper retardation plate formed above the liquid crystal cell; and

    an upper polarizer formed above the upper retardation plate,wherein the user retardation plate has first and second upper retardation plates whose phase retardation axes are different in their direction from each other as seen from the to and which are made of a low dispersion film.
