Abstract

Disclosed is an in-plane switching liquid crystal display. The in-plane switching liquid crystal display uses at least one A-plate and adjusts the optical axis direction and the retardation value of the A-plate, thereby improving the contrast characteristic at a front and at a predetermined inclination angle of the in-plane switching liquid crystal display while minimizing a color shift according to viewing angles in the black state.
