ABSTRACT:
A liquid crystal display device comprises: a first substrate having a first polarization layer on a light incident side; a second substrate having a second polarization layer on a light outgoing side; a liquid crystal layer disposed between the first and the second substrates; a first birefringent film disposed between the first and the second polarization layers; a second birefringent film disposed between the first birefringent film and the second polarization layer; and wherein the liquid crystal layer has a property that a refractive index anisotropy is induced in it by an electric field applied between the pixel electrodes and the common electrode; wherein in-plane retarded phase axes of the first and the second birefringent films form an angle of from 88 degrees to 92 degrees with the first polarization layer; wherein the first birefringent films have Nz coefficients greater than 0.5 and smaller than 0.5, respectively.
