The phase separation by photo-polymerization improves controllability of the structure of the liquid crystal/polymer composite material layer. In particular, the shape of the polymer phase with respect to the liquid crystal phase is precisely controlled to adjust the optical characteristic performance of liquid crystal domains in a connected phase of liquid crystal; to improve the electro-optical characteristics in a low temperature region, and to obtain a display of high contrast and low hysteresis.
