Hologram display device

A hologram display device comprising:

• a spatial light modulator which displays a holographic content image;
• a surface light source device which generates image display light of a first resolution from behind the spatial light modulator and provides the image display light of the first resolution to the spatial light modulator as background light;
• and
• at least one image transmission member which defines a display path of the holographic content image,
• wherein the spatial light modulator generates a holographic content image of a second resolution by the image display light of the first resolution as the background light, and the at least one image transmission member defines a display path of a holographic content image of a third resolution in which the image display light of the first resolution and the holographic content image of the second resolution are mixed, wherein the surface light source device generates the image display light of the first resolution as the surface light source by converting holographic content image data input from the outside into holographic content image data of the first resolution, converting the holographic content image data of the first resolution into an analog image signal, and supplying the analog image signal to organic light-emitting pixels of an organic light-emitting display unit.
