A light deflector which deflects incident light and emits the deflected light, by changing a refractive index of a liquid crystal: a pair of ITO films; a plurality of prisms which are provided between the pair of transparent electrodes and are arranged on a facing surface of one of the pair of transparent electrodes, the facing surface facing a surface of the other one of the pair of transparent electrodes; two spacers arranged between the pair of transparent electrodes, and having, in a direction from one of the pair of transparent electrodes toward the other, widths which (i) are greater than widths of the prisms and (ii) are identical to each other; and a liquid crystal which is provided, within a space between the pair of transparent electrodes, in a portion other than a portion where the prisms and the two spacers exist.
