METHOD OF ORIENTING A LIQUID CRYSTAL MATERIAL, APPARATUS THEREFOR, AND LIQUID CRYSTAL DEVICE ORIENTED THEREBY

摘要

A uniform orientation can be brought about to the liquid crystal material enclosed in a liquid crystal device by applying a shearing force to the liquid crystal material while an electric field is being applied to the liquid crystal material, without requiring disposition of orientation layers nor accurate control of temperature. The orientation method can be efficiently conducted by an apparatus comprising a supply roll for supplying and conveying the liquid crystal device, a roller having conductive orientation rolls for bending the conveyed liquid crystal device and for applying an electric field to the liquid crystal material, a power source for applying a voltage to the conductive orientation roll, and a receiving means for receiving the liquid crystal device which has gone through the bending.
