Abstract
A presentation device according to the present invention includes a panel-shaped image-forming optical element and a flat panel display, and forms a video picture (image) appearing on the display as a spatial image in space over the image-forming optical element. Between the upper surface of the image-forming optical element and the spatial image, a plate (guide plate) having an opening corresponding to the planar shape of the image-forming optical element is disposed at an attitude inclined upwardly from the front toward the back side with respect to the image-forming optical element, whereby the spatial image floats up through the opening of the guide plate. This allows anyone to view a three-dimensional spatial image rich in a sense of depth without experience and skill automatically in an appropriate direction from an appropriate position.
