<p>The present invention relates to an electro-holographic display method which makes a reconstructed image of a hologram focus on an up-and-down or left-and-right space on the hologram, forms the reconstructed image and an image on a display surface of the hologram centering around an optical axis of an image optical system using the optical system and separates the two images completely, shows only the image of the reconstructed image by covering the image of the display surface of the hologram not to be shown to a viewer, and reduces expansion of contrast of the reconstructed image and danger of damaging a viewer′s eyes by putting polymer dispersed liquid crystal (PDLC) and a diffusing plate in which a similar diffusing factor is low, on the image of the reconstructed image.</p> |
