Abstract
A liquid crystal display device of an in-plane switching mode comprises a pair of polarizing plates which are constituted with a polarizing plate at the output side comprising a polarizer at the output side and a polarizing plate at the incident side comprising a polarizer at the incident side having a transmission axis approximately perpendicular to a transmission axis of the polarizer at the output side and two or more sheets of optically anisotropic members and liquid crystal cells disposed between the pair of polarizing plates. The device exhibits excellent scratch resistance and excellent quality of black depth and uniform and high contrast in viewing at any angles.
