The invention relates to a holographic viewing device that enables a bright reconstructed pattern to be viewed in place of light sources in a scene while a spot due to zero-order transmitted light is kept unnoticeable, and a computer-generated hologram for the same. The invention provides a holographic viewing device comprising a frame and a computer-generated hologram fitted in the frame. The computer-generated hologram is constructed as a transmission Fourier transform hologram. The computer-generated hologram comprises minuscule cells having pitches δx and δy with a reconstruction image area defined by a range of spreading of ± first-order diffracted light of given wavelength from a diffraction grating having grating pitches 2δx and 2δy that are twice as large as said pitches of cells, and an input image pattern 35 reconstructed at that wavelength is recorded in the computer-generated hologram in such a way that a light portion 36 of the input image pattern overlaps the center of the reconstruction image area.
