Abstract
A liquid crystal display device of the present invention is arranged such that a retardation of a liquid crystal layer which obtained while no voltage is applied falls within ±(a value which is one-tenth of a main wavelength) of a value obtained by adding natural number times the main wavelength to a total retardation of at least one optical compensation film. This allows suppression of a transmittance during no voltage application.
