Abstract
Disclosed is an in-plane switching liquid crystal display, which uses a positive biaxial retardation film while adjusting an optical axis direction and the retardation value of the positive biaxial retardation film. The in-plane switching liquid crystal display improves the contrast characteristic at a predetermined angular position as well as at a front position thereof, so a color shift according to the viewing angle in the black state is minimized.
