Abstract：
 This invention relates to a method for manufacturing oriented layer of liquid crystal display by soft-carving technique, which belongs to the technical sphere of LCD preparation. The method comprises following steps: a) manufacturing a master blank provided with surface relief micro-patterns; b) transmitting the patterns to the surface of solidified elastomeric polymer by means of surface copy to get a soft-signet with micro-patterns; c) taking the liquor of soluble polymer as 'link'; d) pressing the 'link' on the substrate surface by using said soft-signet; e) uncovering the signet to get the liquid crystal oriented layer for inducing liquid crystal molecular orientation.
