The present invention provides a three-dimensional image display device capable
of reproducing clear, deviation-free and distortion-free three-dimensional images
generated by a three-dimensional generating method. The three-dimensional image
display device 4 comprises a lens array 1 having the predetermined
number of convex lenses arranged in a matrix; and image display means for displaying
a plurality of two-dimensional images 3 corresponding to the respective
convex lenses. The same lens array 1 is employed in the three-dimensional
display device as the lens array employed for generating the two-dimensional images.
