Abstract:
1. An in-plane switching mode liquid crystal display, comprising a liquid crystal cell filled with liquid crystal molecules having positive dielectric anisotropy (Δε>0) which are horizontally aligned between two substrates, placed between a first polarizer and a second polarizer, respective absorption axes of which are perpendicular to each other, wherein a) a first negative (−) biaxial retardation film, arranged adjacent to the liquid crystal cell in such a manner so that its optical axis is perpendicular to an optical axis of the liquid crystal cell; b) a second negative (−) biaxial retardation film, arranged adjacent to the second polarizer in such a manner so that its optical axis is perpendicular to an absorption axis of the second polarizer; and c) a +C-plate arranged between the first negative (−) biaxial retardation film and the second negative (−) biaxial retardation film, are provided between the liquid crystal cell and the second polarizer.
