Abstract:
1. An image display device, comprising: a light source including a plurality of semiconductor light-emitting elements, parallelizing means including a plurality of cell lenses arranged in a one-to-one correspondence with each of said plurality of semiconductor light-emitting elements, an image display element for forming an optical image, a pair of lens-array groups located between said parallelizing means and said image display element, and projection means for enlarging and projecting said optical image formed on said image display element, wherein said plurality of semiconductor light-emitting elements are located at substantially focal points of said cell lenses of said parallelizing means, and there exist at least two types of semiconductor light-emitting elements' groups, light beams on optical axes of said semiconductor light-emitting elements belonging to said two types of semiconductor light-emitting elements' groups existing on straight lines which are different from optical axes of said lens-array groups.
