A display apparatus includes a display unit that projects an image to a light transmissive display member. The display unit is configured to accommodate a display device and a projection optical system that projects the image displayed on the display device to the display member in a housing including an opening through which projected light is output. The projection optical system includes a first reflecting member disposed on a display device side and a second reflecting member disposed on an opening side in an optical path extending from the display device to the opening. A reflection surface of the first reflecting member that reflects the image displayed on the display device has a convex shape of a free-form surface, and a reflection surface of the second reflecting member that projects the image to the display member has a concave shape of a free-form surface.

Systems and methods herein are directed to providing a visual effect background that may be added behind a transparent holographic projection screen (e.g., of a Pepper's Ghost Illusion system) that provides for greater scenic depth behind the holographic projection, regardless of the amount of actual physical space behind the transparent screen. The background, which may be used for projection-based holographic projections or video panel display projections, generally establishes an optical illusion of depth behind the holographic images (producing a depth perception or “perspective” that gives a greater appearance of depth or distance behind a holographic projection).
