    Abstract: An image display device includes a main light source configured to emit a first light; a display panel configured to modulate the first light to add image information to the first light; a holographic optical element (HOE) configured to diffract the first light emitted from the display panel to make the first light travel to a first region to generate a main image; a first optical system provided on a traveling path of the first light between the main light source and the HOE, the first optical system being configured to change the traveling path of the first light to be incident on the HOE along a first path; an auxiliary light source configured to emit a second light; and a second optical system provided on a traveling path of the second light, the second optical system being configured to change a traveling path of the second light to be incident on the HOE along a second path different from the first path.

    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.
