A liquid crystal display device has a liquid crystal cell including first and second substrates spatially arranged to oppose each other, first and second electrodes formed on opposing surfaces of the first and second substrates, respectively, and a liquid crystal composition filled between the first and second substrates and arranged in a twisted mode. First and second polarizers are arranged on both sides of the liquid crystal cell. An optical retardation film is arranged between the first substrate and the first polarizer. The optical retardation film has a retardation value falling within a range of RO.times.0.55 to RO.times.0.80 where RO is a retardation of the liquid crystal cell. An optical axis of the optical retardation film is angled 100.degree. to 130.degree. with respect to the alignment direction of the liquid crystal molecules on the first substrate.
