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.

Abstract: A light deflector includes a first light deflecting member disposed on a transparent substrate and has a refractive index that varies depending on a magnitude of an electric field applied thereto. The light deflector may adjust the refractive index by applying electric fields differently according to regions of the first light deflecting member or time divisions. The light deflector may have a smaller size than a light deflector including an optical device, and may easily adjust the refractive index.
