Abstract
A liquid crystal display device comprising a first optical compensating member disposed without a birefringent medium sandwiched between a liquid-crystal layer and the first optical compensating member. The first optical compensating member is constructed so that when a refractive index thereof in a slow-axis direction in a plane parallel to the substrate is taken as n1, a refractive index in a fast-axis direction in the plane parallel to the substrate is taken as n2, and a refractive index in a thickness direction is taken as n3, the first optical compensating member satisfies n1˜n3>n2 and a slow axis thereof in the plane parallel to the substrate is substantially vertical to an optical axis of the liquid-crystal layer.
