Image display device

An image display device, comprising:

• a display that displays an image by outputting light from the display to a plurality of micro-lenses;
• and
• a display controller that controls displaying the image, by the display, by (1) outputting first light from the display through a first micro-lens among the plurality of micro-lenses, (2) outputting second light from the display through a second micro-lens among the plurality of micro-lenses, (3) outputting third light from the display through the first micro-lens and (4) outputting fourth light from the display through the second micro-lens, thereby forming a three-dimensional image having spatial depth, wherein:
• the first light at a first position and the second light at a second position form the three-dimensional image, with a distance between the first position and the display being different from a distance between the second position and the display,
• the first light and the fourth light intersect at the first position and the second light and the third light intersect at the second position, and
• the first and second micro-lenses are adjacent to each other.
