ABSTRACT:
The present invention provides a liquid crystal display device of VA mode having decreased leakage of light over a wide range and giving a clear and almost achromatic black display by using a retardation film A having smaller retardation with shorter wavelength in combination with a retardation film C having larger retardation with shorter wavelength. Accordingly, a high-quality liquid crystal display device having excellent picture quality can be produced by the present invention.
