ABSTRACT:
The image display device is configured to include the light source including a plurality of semiconductor light-emitting elements, a parallelizing unit including a plurality of cell lenses arranged in a one-to-one correspondence with each of the plurality of semiconductor light-emitting elements, an image display element for forming an optical image, a pair of lens-array groups located between the parallelizing unit and the image display element, and a projection unit for enlarging and projecting the optical image formed on the image display element. Moreover, the plurality of semiconductor light-emitting elements are located at substantially focal points of the cell lenses of the parallelizing unit. Furthermore, there exist at least two types of semiconductor light-emitting elements' groups, light beams on optical axes of the semiconductor light-emitting elements belonging to the two types of semiconductor light-emitting elements' groups existing on straight lines which are different from optical axes of the lens-array groups.
