Abstract
The present invention relates to an in-plane switching liquid crystal display comprising a negative biaxial retardation film and a positive C-plate, as viewing-angle compensation films. By the use of such viewing-angle compensation films, the contrast characteristics at the front side and inclination angle of the in-plane switching liquid crystal display can be improved and color shift with viewing angle in the dark state can be minimized.
