A bistable nematic liquid crystal display device comprises two opposed cell walls (1) enclosing a layer of a nematic liquid crystal material (6). An inner surface of each cell wall (1) is provided with an electrode (2) for applying an electric field across at least some of the liquid crystal material (6). An inner surface of one of the cell walls (1) is provided with a surface alignment (4) capable of inducing a desired alignment in adjacent molecules of the liquid crystal material (6), and a layer of finely-divided particles (5) is immobilised on the surface alignment (4). |
