Abstract
An illumination device comprises: a plurality of laser light sources arranged so as to be identical in a direction of light emission; an optical element for converting laser light emitted from the laser light sources into parallel light at least in one direction; and a fly-eye lens into which the laser light converted into parallel light is entered. Placement of the laser light sources is adjusted in such a manner that incident regions of the laser light on the fly-eye lens are mutually shifted in a row or column direction of lens cells disposed in the fly-eye lens.
