PROBLEM TO BE SOLVED: To realize a three-dimensional image display method and its display device manufacturing is easy and in which particle shapes of lenses are not conspicuous and whose image-froming performance is satisfactory and which is capable of displaying three-dimensional images by using lenses having sufficient brightness. SOLUTION: This three-dimensional image display device is provided with a lens array 10 in which plural lenses are two-dimensionally arranged and original pictures 2' in which minute inverted images or Fourier transformation images of reproduced images are recorded or displayed according to respective lenses consisting of the lens array 10 and which forms images corresponding to original pictures 2', the lens array 10 is composed in such a manner that plural radial type refractive index distribution type lenses are two-dimensionally arranged so that optical axes of the lenses become parallel each other. |
