Abstract:
A liquid crystal display device of an in-plane switching mode comprises at least optically anisotropic members (A) and (B) and a liquid crystal cell disposed between a pair of polarizers having absorption axes disposed approximately perpendicularly to each other, wherein nzA>nyA and nxB>nzB (nxA, nxB: refractive indices (n) in the direction of the in-plane slow axis; nyA, nyB: n in the in-plane direction perpendicular to the above direction; nzA, nzB: n in the direction of thickness, each at 550 nm); the in-plane slow axes of (A) and (B) are approximately parallel or perpendicular to each other; and the in-plane slow axis of (A) is approximately parallel or perpendicular to the absorption axis of a polarizer closer to (A). The antireflection property, scratch resistance and durability are excellent, the angle of field is wide, and uniform display of images with great contrast can be achieved at any angle of observation.
