Abstract: Disclosed herein is a holographic display which enables stereoscopic display of colors by changing a structure and mitigates a flickering effect by lowering the response speed. The holographic display may deliver an image to different positions for the left eye and right eye at the same time, thereby lowering the frequency necessary for supply of holographic image information. Thereby, the holographic display may address the issues of the afterimage effect and flickering effect in a liquid crystal panel-based spatial light modulator.
