Abstract
A light distribution control device includes: first upper electrodes and second upper electrodes disposed alternately in a first direction; first lower electrodes and second lower electrodes disposed alternately in a second direction that crosses the first direction; light transmissive regions disposed between an upper electrode set consisting of the first upper electrodes and the second upper electrodes and a lower electrode set consisting of the first lower electrodes and second lower electrodes; and colored electrophoretic particles and a dispersion medium contained in a space between light transmissive regions. Each of the first upper electrodes extends along the space between light transmissive regions. Each of the second upper electrodes extends along a line of light transmissive regions. Each of the first lower electrodes extends along the space between light transmissive regions. Each of the second lower electrodes extends along a line of light transmissive regions.
