摘要:
This invention provides a vertically aligned liquid crystal display, including a first polarizing plate and a second polarizing plate having absorption axes perpendicular to each other and a vertically aligned panel provided therebetween and including vertically aligned liquid crystals having negative dielectric anisotropy, in which a +A-film and a +C-film are provided between the first polarizing plate and the vertically aligned panel, the +C-film is positioned between the first polarizing plate and the +A-film, and the optic axis of the +A-film is parallel to or perpendicular to the absorption axis of the first polarizing plate. According to this invention, the contrast of the vertically aligned liquid crystal display can be improved at surface-facing angle and tilt angle thereof and the color shift depending on the viewing angle in a dark state can be minimized, thus greatly increasing the viewing angle range of the vertically aligned liquid crystal display.
