Abstract
Disclosed herein is an IPS-LCD using two sheets of negative (−) biaxial retardation films and one +C-plate. The IPS-LCD has a superior contrast ratio at the surface-facing angle and tilt angles and undergoes a minimal color change with viewing angles in a black state, thereby providing a wider viewing angle.
