Abstract
A display device includes a light source part including a first light source and a second light source, a collimation lens that collimates light incident from the light source part, a wave guide that guides and diffracts the light incident from the collimation lens, a spatial light modulator that modulates the light passing through the wave guide so as to form a holographic pattern for reproducing a holographic image, a focusing optical system that focuses the holographic image on a space, and a light separating plate disposed between the light source part and the collimation lens, the light separating plate separating light of the first light source and light of the second light source from each other.
