Liquid crystal ͑LC͒ cells consisting of a very thin ͑submicrometer͒ nematic LC layer switch with time response smaller than 1 ms. The total response time, i.e., sum of the turn-on and turn-off times, can be made as small as 1.3 ms. Such devices were prepared by a photoinduced anisotropic phase separation of mixtures of the LC and prepolymer. The formation of the LC-polymer bilayer in these devices was confirmed by polarized light microscopy and scanning electron microscopy. The phase separation
