A light beam direction control element includes light transmission regions interposed between a first light transmission substrate and a second light transmission substrate, light absorption regions located between the light transmission regions, a light transmission dispersion medium enclosed in the light absorption regions, and electrophoretic particles dispersed in the light transmission dispersion medium. The light transmission regions include a first light transmission region extending from the first light transmission substrate toward the second light transmission substrate, and a second light transmission region extending from the first light transmission region toward the second light transmission substrate. A height of the first light transmission region is lower than a height of the second light transmission region and a width of the first light transmission region is wider than a width of the second light transmission region.
