Abstract
The present invention relates to a nematic bistable display device, characterized in that it comprises control means () for producing, after the anchoring is broken, hybrid textures in which two bistable textures coexist in a controlled proportion within the same pixel, these being separated by 180° volume disclination lines or by 180° reorientation walls on one of the surfaces, and means () for the long-term stabilization of the hybrid textures by transformation of the volume lines into surface walls and the immobilization of these walls on the surface.
