PROBLEM TO BE SOLVED: To provide a retroreflective display body of high conspicuity which is capable of calling increased attention even at night.SOLUTION: A display is drawn on the front surface of a reflector having retroreflectivity and is caused to include a solid figure formed by planarly combining a plurality of display areas different by light transmittance, and light beams which pass the respective display areas and retroreflect to the reflector are emitted from the respective display areas as reflected light, and shades of the solid figure are expressed by difference of reflection brightness among the respective display areas due to the difference of the light transmittance. Bright parts of the solid figure are expressed by strong reflected light of display areas having high reflection brightness, and shaded parts are expressed by weak reflected light of display areas having low reflection brightness or non-reflection, so that the solid figure is viewed more stereoscopically. |
