DISPLAY DEVICE AND ILLUMINATION METHOD
To provide a display device which has a high degree of freedom in installation and which enables a user to confirm displayed information even in a dark place from a distance and an illumination method using such an illumination device.SOLUTION: A display device 1 comprises: a portable illumination device 10; and a portable connector 30 that connects the illumination device 10 and a support 20 that supports the illumination device 10. The illumination device 10 includes: a light source that emits coherent light; and a diffraction optical element that diffracts the coherent light from the light source and directs the same to an illuminated surface 95. The illumination device 10 presents information according to a diffraction pattern of the diffraction optical element.SELECTED DRAWING: Figure 1A
【課題】設置の自由度が高く、表示する情報を暗所においても遠くから確認することが可能な表示装置、及び、そのような照明装置を用いた照明方法を提供する。【解決手段】表示装置１は、可搬性の照明装置１０と、照明装置１０と照明装置１０を支持する支持体２０とを接続する可搬性の接続具３０と、を有する。照明装置１０は、コヒーレント光を射出する光源と、光源からのコヒーレント光を回折して被照射面９５に向ける回折光学素子と、を有している。照明装置１０は、回折光学素子での回折パターンに応じた情報を示す。【選択図】図１Ａ
