SPATIAL FLOATING IMAGE DISPLAY DEVICE

WIPO Patent Application WO/2023/176159

A1

The purpose of the present invention is to provide a technology with which it is possible to reduce the thickness of a spatial floating image display device and reduce the influence of heat from a light source device and the like.　This spatial floating image display device comprises: a light source device (30) provided with a light source part (31A); an image display element (11) which emits image light on the basis of light from the light source device (30); and a retroreflective member (5) which reflects the image light from the image display element (11) to form, in the air, a spatial floating image (3) that is a real image by the reflected light. A flexible cable (703) or a substrate (704) to be connected to the image display element (11) is disposed so as to bypass the light source part (31A) of the light source device (30) such that a space is created therebetween and go around to the back surface side of the light source device (30).
