PROBLEM TO BE SOLVED: To provide an image display device that can prevent an increase in cost, and can allow observation of different images from a plurality of observation areas and observation of a common image by a plurality of observers in each observation area, without imposing a physical burden on each observer.SOLUTION: An image display device 100 includes a reflection part 1 and a plurality of projectors 2. The reflection part 1 is provided so as to cover a field 51. Spectator stands 52 are set with a plurality of observation areas 52a so as to be arranged in a circumferential direction of the field 51. The plurality of projectors 2 are respectively provided to correspond to the plurality of observation areas 52a. The projectors 2 emit a light beam group including a plurality of light beams toward the reflection part 1. The reflection part 1 includes a plurality of retroreflective elements 1a, and reflects and diffuses the light beam group emitted from the projectors 2 toward the corresponding observation areas 52a.SELECTED DRAWING: Figure 2 |
