<P>PROBLEM TO BE SOLVED: To switch a two-dimensional mode and a three-dimensional mode by using two microretarders so that an observer can recognize a two-dimensional image and a three-dimensional image. <P>SOLUTION: The display device includes a spatial optical modulator (1), two microretarders (2 and 3) having several fringes overlapping each other and arranged behind the spatial optical modulator, a polarizer (4) arranged behind the two microretarders, a back light (5) arranged behind the polarizer, 1st and 2nd driving devices (6 and 7) and a carrier (8). The two-dimensional image and the three-dimensional image are selectively displayed in accordance with the relative horizontal movement of the two microretarders. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
