Abstract
A three-dimensional image display device which comprises a light source; a hologram divided into a plurality of divided areas and exposed so that point images are formed at different positions in a three-dimensional space in the respective divided areas when the light from the light source is irradiated; a hologram driver unit for driving the hologram such that light from the light source is selectively entered into one of the plurality of divided areas and; a control unit for controlling the lighting up of the point images formed in the three-dimensional space in correspondence to a three-dimensional image signal by controlling the hologram and the light source in accordance with the three-dimensional image signal to be displayed, whereby a three-dimensional image is obtained by the hologram with the simple-configured device.
