Abstract: A liquid crystal light deflector includes a first electrode layer including line electrodes, a second electrode layer including a common electrode, and a liquid crystal layer that forms an electrical prism using liquid crystal molecules according to an electric field formed between the first and second electrode layers. The orientations of the liquid crystal molecules may be reset by an electric field formed between line electrodes of adjacent channels within the first electrode layer. A method of deflecting light includes controlling the first electrode layer and the second electrode layer to reset the orientation of the liquid crystal molecules prior to forming an electrical prism in the liquid crystal layer.
