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.
