Liquid crystal display device

A liquid crystal display device comprising:

• a liquid crystal display panel which is configured such that a liquid crystal layer including homogeneously aligned liquid crystal molecules is held between a first substrate and a second substrate which are disposed to be opposed to each other;
• a first optical element which is provided on one of outer surfaces of the liquid crystal display panel and includes a first polarizer plate, a first retardation plate which is disposed between the first polarizer plate and the liquid crystal display panel and imparts a phase difference of ½ wavelength between light rays of a predetermined wavelength which pass through a fast axis and a slow axis of the first retardation plate, and a second retardation plate which is disposed between the first retardation plate and the liquid crystal display panel and imparts a phase difference of ¼ wavelength between light rays of a predetermined wavelength which pass through a fast axis and a slow axis of the second retardation plate, and the second retardation plate being formed such that nematic liquid crystal molecules are solidified in a state in which the nematic liquid crystal molecules are hybrid-aligned in a normal direction;
• and
• a second optical element which is provided on the other outer surface of the liquid crystal display panel and includes a second polarizer plate, a third retardation plate which is disposed between the second polarizer plate and the liquid crystal display panel and imparts a phase difference of ½ wavelength between light rays of a predetermined wavelength which pass through a fast axis and a slow axis of the third retardation plate, a uniaxial fourth retardation plate which is disposed between the third retardation plate and the liquid crystal display panel and imparts a phase difference of ¼ wavelength between light rays of a predetermined wavelength which pass through a fast axis and a slow axis of the fourth retardation plate, and a fifth retardation plate which is disposed between the fourth retardation plate and the liquid crystal display panel,
• wherein the fifth retardation plate has a refractive index anisotropy of nx≅ny>nz, where nx and ny are refractive indices in mutually perpendicular directions in a plane of the fifth retardation plate, and nz is a refractive index in a normal direction of the fifth retardation plate.
