Liquid crystal display with twist angle less than 80 degrees

Claim 1

A liquid crystal display comprising: two parallel support plates separated by a peripheral border to form a cell in the space between said plates and said border; a layer of nematic liquid crystal with positive dielectric anisotropy filled in said cell; electrode coatings formed on inside surfaces of said plates; first and second orientation coatings formed on respective of said electrode coatings, said orientation coatings defining orientation directions enclosing an angle (α) less than 80°, a first polarizer associated with said first orientation coating and having a polarization direction which runs parallel to the orientation direction of said first orientation coating; a second polarizer associated with said second orientation coating and having a polarization direction which runs perpendicular to the orientation direction of the second orientation coating; said polarizers having an extinction power greater than 100; said liquid crystal layer having a thickness (d) and defining an anisotropy of an index of refraction (Δn) the product of which is less than 1.3 μm; and a dichroic dye of up to 3% by weight added to the liquid crystal layer.
