Patent ID: 8269930

Claim:
A liquid crystal display (LCD) device comprising: a liquid crystal display panel having a liquid crystal layer; a first polarizer and a second polarizer respectively disposed at upper and lower portions of the liquid crystal display panel to polarize light; a positive C-film disposed between the first polarizer and the liquid crystal display panel to change a polarized state of light, the positive C-film having a retardation value of Re=0 nm in a horizontal direction and a retardation value of Rth=−50˜−200 nm in a thickness direction; and a positive biaxial film disposed between the liquid crystal display panel and the second polarizer to change a polarized state of light, the positive biaxial film having a retardation value Re=80˜160 nm in a horizontal direction and a retardation value of Rth=−24˜−160 nm in a thickness direction, wherein Re=(n x −n y )d and Rth=(n x −n z )d, where n x , n y and n z respectively denote a refractive index in x-axial direction, a refractive index in y-axial direction and a refractive index in z-axial direction.
