Abstract
A display medium displays a predetermined number of contents corresponding to a predetermined number of azimuth angles when viewed from a predetermined elevation angle and azimuth angle. An example display medium includes: a planar member that reflects light; and a plurality of protruding members, each protruding member of the plurality of protruding members has a surface occluding the light, placed vertically on the planar member and parallel to each of the predetermined number of azimuth angles. The planar member is partitioned into a plurality of unit cells, where each unit cell is further partitioned into the predetermined number of sub-cells corresponding to the predetermined number of azimuth angles. The protruding member that has the surface parallel to the predetermined azimuth angle is formed for each sub-cell corresponding to the predetermined azimuth angle.
