<P>PROBLEM TO BE SOLVED: To provide a three-dimensional image display device that enables an observer to recognize a color three-dimensional image in a superior visibility state even when the three-dimensional image display device is rotated by 90° from a normal observation direction, a portable terminal device mounted thereupon, and a display panel and a lens which are incorporated in the three-dimensional image display device. <P>SOLUTION: In a three-dimensional image display device 1 for displaying color three-dimensional images, a fly eye lens 3, a display panel 2, and a light source are provided in this order from the observer side. The display panel 2 has four pixels arrayed in a (2×2) matrix correlated with one lens element of the fly eye lens 3. In the event that (j) is a natural number, a pixel magnifying projection width (e) in a second direction 22 is set in a range of a mathematical expression 1 according to the both eyes spacing Y of the observers. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
