Abstract

The invention relates to a liquid-crystal display device comprising a display cell and a plurality of retardation foils of polymerized or vitrified liquid-crystal material, whose liquid-crystal molecules have a tilt angle with respect to a plane parallel to the substrates, which retardation foils have substantially complementary indicatrices so that each one of the retardation foils brings about the compensation of approximately half the display cell in the driven state.
