发明名称 Liquid crystal display device
摘要 <p>A NW mode TN-LCDs having significantly improved viewing angle characteristics of both display contrast and gray scale inversion, wherein a optical compensation layer (A) having a characteristic wherein the refractive index in the thickness direction of the film is lower than that in-plane of said film; a optical compensation layer (B) having optically positive refractive index anisotropy and having a characteristic wherein the principal optic axis thereof is tilted 20 to 70 DEG from the normal direction of the film; a uniaxial optical compensation layer(C)having optically positive refractive index anisotropy; a polarizing film(PL); a liquid crystal cell(LCC); are laminated in the following order: (1) PL, A, B, LCC, B, A, PL or (2) PL, A, B, C, LCC, C, B, A, PL.</p>
