Patent ID: 8599340

Claim:
A liquid crystal display device comprising: a liquid crystal display panel having a liquid crystal layer; a first polarizer and a second polarizer located below and above the liquid crystal display panel, respectively, to polarize light; a negative A-film provided between the liquid crystal display panel and the first polarizer to change a light polarized state, the negative A-film having a retardation value Re of −150˜30 nm in a horizontal direction and a retardation value Rth of 0 nm in a thickness direction; and a positive biaxial film provided between the liquid crystal display panel and the second polarizer to change a light polarized state, and the positive biaxial film having a retardation value Re of 180˜240 nm in a horizontal direction and a retardation value Rth of −60˜0 nm in a thickness direction, wherein Re=(n x −n y )d, Rth=(n x −n z )d, and n x , n y and n Z denote refractive indexes of x, y and z-axial directions, respectively.
