| description | To provide a display unit that reduces the constraints on the manufacture of the device and allows a plurality of observers facing each other to visually recognize different image from both sides.SOLUTION: A display unit 1 comprises: a total reflection mirror and a display panel that face each other; a polarization selection mirror that is installed inclined between them; and a 1/4 wavelength plate that is arranged overlapped on any one of the total reflection mirror and the polarization selection mirror. The display unit 1 is installed such that both a first observer and a second observer can visually recognize real images through the polarization selection mirror. The display panel displays a first image and a second image that are two types of independent images having a first polarization direction and a second polarization direction orthogonal to each other. The polarization selection mirror reflects the first image in a direction in which the first observer can visually recognize the image, and transmits the second image, and after the image is deflected through the 1/4 wavelength plate and the total reflection mirror, reflects the image in a direction in which the second observer can visually recognize the image.SELECTED DRAWING: Figure 1
【課題】装置の製造上の制約を低減させ、互いに対向する複数の観察者について、双方から異なる画像を視認させる表示装置を提供する。【解決手段】本実施の形態に係る表示装置１は、互いを対向させた全反射ミラー及び表示パネルと、それらの間に傾斜して設置される偏光選択ミラーと、全反射ミラー及び偏光選択ミラーのいずれか一方に重ねて配置した１／４波長板と、を備える。表示装置１は、偏光選択ミラーを介して第１観察者と第２観察者とが互いに実像を視認可能な状態で設置される。表示パネルは、互いに直交する第１偏光方向及び第２偏光方向を有する独立した２種の画像である第１画像及び第２画像を表示する。偏光選択ミラーは、第１画像を第１観察者が視認可能な方向へ反射させ、且つ、第２画像を透過させ、１／４波長板及び全反射ミラーを介して偏光された後、第２観察者が視認可能な方向へ反射させる。【選択図】図１ |
