ABSTRACT:
A liquid crystal display device includes a liquid crystal panel, a polarizer plate that is disposed on an observer side, relative to the liquid crystal panel, a polarizer plate that is disposed to be opposed to the polarizer plate, with the liquid crystal panel interposed, and an optical film that is disposed between the polarizer plate and the liquid crystal panel and between the polarizer plate and the liquid crystal panel, thereby to increase a viewing angle of an image that is displayed by the liquid crystal panel, wherein a twist angle of the liquid crystal molecules sealed in the liquid crystal panel is greater than 90° and not greater than 96°, a retardation Δnd of the liquid crystal panel is between 400 nanometers (nm) and 430 nm, and a retardation Δnd of the optical film is between 110 nm and 120 nm.
