Display apparatus

Abstract

A display apparatus is configured to display an aerial image by using retroreflection. The display apparatus includes a light source; a beam splitter configured to reflect light output from the light source; and a plurality of retroreflective materials configured to reflect light from the beam splitter in a same direction as incident light. The plurality of retroreflective materials include at least three retroreflective materials that are arranged in a range where the aerial image can be observed, and the plurality of retroreflective materials are in a positional relationship such that at least one side of each of the retroreflective materials is overlapping with a side of an adjacent retroreflective material.
