Abstract
A liquid crystal display comprises two parallel spaced substrates and a liquid crystal layer with negative dielectric anisotropy interposed between the substrates. The ratio d/p, the cell gap d between the substrates to the pitch p of the liquid crystal layer, is equal to or less than 0.3, and the retardation value Δn*d may be in the range of 0.25-0.4. In absence of electric field, the liquid crystal molecules are arranged vertically to the substrates, and when the sufficient electric field is applied, the liquid crystal molecules are parallel to the substrates and twisted by 90° from one substrate to the other.
