Abstract
A holographic display apparatus for providing an expanded viewing window is provided. The holographic display apparatus includes a spatial filter configured to allow a plurality of holographic images generated by 0th order or higher diffraction in a spatial light modulator to pass therethrough, and an image path conversion element configured to adjust a light path of the plurality of holographic images so that the plurality of holographic images are spaced apart from each other on a focal plane of an optical system.
