PROBLEM TO BE SOLVED: To make it possible to display three-dimensional image on an image output device and to facilitate to do other tasks while watching the three- dimensional image. SOLUTION: This device is provided with a two-dimensional image display part 11 formed by two-dimensionally arraying a plurality of light emitting elements, a varifocal lens 13 being arranged corresponding to each light emitting element and passing the light from each light emitting element therethrough, a light emitting element driving means for making each light emitting element emit according to a display data, and a focus distance setting means for setting the focus distance of the varifocal lens 13 correspondingly to the emission of each light emitting element of the above. In this case, the light emitting element driving means makes each light emitting element emit light according to the display data and the focus distance setting means sets the focus distance of the varifocal lens 13 correspond to each light emitting element of the above, and thus, a three-dimensional image can be displayed. |
