Patent ID: 8199283

Claim:
A liquid crystal display device comprising: first and second polarizers in cross Nichol configuration; a liquid crystal cell disposed between the first and second polarizers and establishing vertical alignment in a state of no voltage application; a first optical film disposed between the liquid crystal cell and the first polarizer and having optical anisotropy; a second optical film disposed between the first optical film and the liquid crystal cell and having optical anisotropy; and a third optical film disposed between the second polarizer and the liquid crystal cell and having optical anisotropy; wherein: each of the first to third optical films satisfies nx>ny≧nz where nx, ny and nz are x-, y- and z-components of a refractive index in which an x-axis is an in-plane slow axis azimuth of each of the optical films, a y-axis is an in-plane azimuth perpendicular to the x-axis and a z-axis is a direction perpendicular to a film surface, an in-plane retardation is larger than 0 nm and equal to or smaller than 300 nm, and a thickness direction retardation is equal to or larger than 50 nm and equal to or smaller than 300 nm; a slow axis of the first optical film is parallel to an absorption axis of the first polarizer; a slow axis of the second optical film and a slow axis of the third optical film are perpendicular to each other; and an angle between the slow axis of the second optical film and the absorption axis of the first polarizer is in a range between 75° and 105°.
