The liquid crystal display device includes a liquid crystal cell having a nematic liquid crystal layer, upper and lower retardation plates sandwiching the liquid crystal cell, an upper polarizer above the upper retardation plate, and a lower polarizer below the lower retardation plate. The nematic liquid crystal layer is arranged at the upper and lower substrates with the twist angle set in a range of 0° to 70° which is subjected to a rubbing process at a predetermined angle relative to a reference direction. The lower retardation plate has a first lower retardation plate of a discotic liquid crystal film with hybrid alignment, and a second lower retardation plate of a polymer film having a three-dimensional refractive index anisotropy. The three-dimensional refractive index of the second lower retardation plate is set in a range of -0.7 to 0.7.
