A holographic display device for displaying a 3-dimensional
image has a cylindrical casing and a horizontally-placed circular
reflection-type hologram in order to project an upright
orthoscopic real image having both horizontal and vertical
parallaxes. The hologram may be illuminated by a point source of
white light, preferably a high-efficiency light emitting diode,
securely attached to telescopic or flexible means integrated into
the holographic display device. The hologram may be rotated by an
electric motor in order to display all sides of the holographic
image. The means for mounting the point source of white light may
have the same diameter as the cylindrical casing in order to
slidably house the cylindrical casing. This invention relates to
holographic display devices for displaying a 3-dimensional image,
and the principal use of the invention is for optical decoration.
