description A light beam direction control element includes a light beam direction controller and a controller. The light beam direction controller includes light transmitting regions sandwiched between a first light transmissive substrate and a second light transmissive substrate, light absorbing regions located between light transmitting regions, a light transmissive dispersion medium sealingly contained in the light absorbing regions, and electrophoretic particles dispersed in the light transmissive dispersion medium. The controller, by controlling voltage applied to the electrophoretic particles from a first light transmissive electrode on the first light transmissive substrate and second light transmissive electrodes and third light transmissive electrodes on the second light transmissive substrate, causes the electrophoretic particles to localize to the second light transmissive substrate side and also causes the electrophoretic particles to flow between a space over each of the second light transmissive electrodes and a space over an adjacent one of the third light transmissive electrode.
