ABSTRACT:
A liquid crystal display including a cell which consists of two cell plates and a liquid crystal with positive dielectric anisotropy layered between the plates, where the molecules of the liquid crystal next to the plates exhibit preferred directions rotated by 90.degree.. The display includes only one polarizer that is placed on the front cell plate. A reflector formed of a layer of insulated metal particles is located inside the cell on the rear plate and exhibits a structure determining the preferred direction of the liquid crystal molecules. The electrode segments are holohedral and the operating voltage applied thereto lies between 1.3 and 2.5 times the Freedricksz threshold voltage.
