BISTABLE NEMATIC LIQUID CRYSTAL DISPLAY DEVICE WITH IMPROVED OPTICAL MASK

摘要

The invention concerns a bistable nematic liquid crystal display device comprising: aligning means, which ensure the orientation of the liquid crystal, means designed for applying electric signals enabling to switch by anchor rupture on at least two substrates, between two separate textures and means for promoting, in the liquid crystal covering the inter-electrode spaces, the installation of that among said textures providing off-state.
