Liquid crystal display device with biaxial birefringent plates and light shielding film

摘要: The liquid crystal display device of the present invention comprises a layer nematic having positive dielectric anisotropy and including chiral material, being interposed between pair substrates with transparent electrodes each an aligning which are arranged substantially in parallel to provide twist angle 160°-300°, driving means apply voltage across attached interpose layer, polarizing plates outside at least one birefringent plate provided side wherein product Δn 1 ·d, refractive index Δn, molecules thickness d, is range 0.4-1.5 μm, three main indices n x , y z relation ≧n >n where respectively represent direction film plane (provided ) represents plate.
