Bistable nematic liquid crystal display device with improved optical mask, having textures differing by about 180° twist, and off state in the liquid crystal covering the inter-electrode spaces
Bistable nematic liquid crystal display device with improved optical mask, having textures differing by about 180° twist, and off state in the liquid crystal covering the inter-electrode spaces
The invention relates to a bistable nematic liquid-crystal device comprising: alignment means, which orient the liquid crystal, means designed to apply electrical signals which allow switching, by breaking the anchoring on at least one of the two substrates, between two distinct textures, and means designed to promote the establishment of that one of the said textures giving the off state in the liquid crystal covering the inter-electrode spaces.
