Method for manufacturing electro-optical device by use of polymer stabilized liquid crystal molecules

• The title method comprises arranging chiral or cholesteric liq. crystal (LC), photoreaction monomers and photosensitive initiator in an LC unit cell, and irradiating primary surface of the LC unit cell via UV light having non-uniform intensity distribution in the LC unit cell. The irradn. matches the photosensitive initiator for polymg. at least partial photoreaction monomers near the primary surface, so as to generate polymer network with d. corresponding to the intensity distribution of the non-uniform UV light, wherein the polymer network makes the LC bias to selected helical arrangement direction.
