Abstract:
1. A liquid-crystal display device comprising first and second polarizing elements, and a liquid-crystal cell disposed between the first and second polarizing elements, wherein: the liquid-crystal cell comprises first and second substrates (provided that the first substrate is disposed closer to the first polarizing element, and the second substrate is disposed closer to the second polarizing element), a liquid-crystal layer disposed between the first and second substrates, a color filter layer disposed on an inner surface of the first substrate, and an in-cell polarizing layer comprising at least a dichroic dye disposed between the color filter layer and the liquid-crystal layer, the absorption axis of the first polarizing element and the absorption axis of the in-cell polarizing layer are parallel to each other, and the sum total of the absolute values of retardation in-plane, Re, of all the layers disposed between the in-cell polarizing layer and the first polarizing element is equal to or less than 10 nm, and the sum total of the absolute values of retardation along the thickness-direction, Rth, of said all of the layers thereof is equal to or less than 15 nm.
