Abstract:
The purpose of the present invention is to provide an image display device and an image display element that are able to produce an excellent visual effect. This image display device is provided with a first transparent member (30), a second transparent member (40), and an emission unit (10). The first transparent member (30) has a diffusion surface (31) for diffusing light incident on respective points. The second transparent member (40) has a control surface (41) that is disposed to face the diffusion surface and forms a virtual image of the diffusion surface by controlling the traveling directions of light diffused at the respective points of the diffusion surface, and is configured integrally with the first transparent member (30). The emission unit (10) emits image light to the diffusion surface (31).
