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